Summary
OpenShift Console Server Side Request Forgery vulnerability
Details

A flaw was found in OpenShift Console. A Server Side Request Forgery (SSRF) attack can happen if an attacker supplies all or part of a URL to the server to query. The server is considered to be in a privileged network position and can often reach exposed services that aren't readily available to clients due to network filtering. Leveraging such an attack vector, the attacker can have an impact on other services and potentially disclose information or have other nefarious effects on the system. The /api/dev-console/proxy/internet endpoint on the OpenShit Console allows authenticated users to have the console's pod perform arbitrary and fully controlled HTTP(s) requests. The full response to these requests is returned by the endpoint. While the name of this endpoint suggests the requests are only bound to the internet, no such checks are in place. An authenticated user can therefore ask the console to perform arbitrary HTTP requests from outside the cluster to a service inside the cluster.

Summary
Budibase: SSRF via DNS rebinding in the REST datasource integration
Details

Summary

Budibase's central outbound-fetch guard (fetchWithBlacklist) prevents SSRF/DNS-rebinding by resolving the target hostname, checking every resolved IP against the blacklist, and pinning the connection to the validated IP. The pin is implemented as a Node http(s).Agent (makePinnedAgent). The fix for CVE-2026-54353 relies on this pin to stop DNS rebinding.

The REST datasource integration (@budibase/server) calls fetchWithBlacklist but performs the actual request with undici's fetch. undici does not support the Node agent option — it is silently ignored — and instead uses its own dispatcher, which re-resolves the hostname's DNS at connection time. As a result, the validated/pinned IP is never used on the REST datasource path, and the DNS-rebinding protection that CVE-2026-54353 added is silently defeated for the single most-used outbound path in Budibase.

An authenticated user who can configure/run a REST datasource (e.g. a builder/tenant) can use a rebinding hostname (public IP during validation, internal IP at connect) to make the server issue arbitrary, full-response HTTP requests to internal-only services — cloud metadata (IAM credential theft), the internal CouchDB/Redis/MinIO, and other internal endpoints — reading and, because REST datasources allow arbitrary method/body, writing or destroying internal data.

Details

The guard pins the validated IP via a Node agentpackages/backend-core/src/utils/outboundFetch.ts:

  • resolveSafePinnedIp(url) resolves the hostname and checks every address against isBlacklisted, returning a single pinnedIp (lines ~39–53).
  • makePinnedAgent(url, ip) builds a Node http.Agent/https.Agent whose lookup always returns pinnedIp, so a node-fetch connection can only reach the validated IP (lines ~55–68).
  • fetchWithBlacklist passes that agent into the request: fetchFn(nextUrl, { ...nextRequest, agent: makePinnedAgent(nextUrl, pinnedIp) }) (lines ~186–192). Each redirect hop is re-validated and re-pinned in the loop.

The REST integration overrides the transport with undici, which ignores agentpackages/server/src/integrations/rest.ts:

  • fetch is imported from undici (top-of-file import block, ~line 30).
  • The request is made by overriding fetchFn (lines ~767–793): ts const setDispatcher = (requestInput, requestUrl) => ({ ...requestInput, dispatcher: getDispatcher({ rejectUnauthorized, url: requestUrl }), }) ... response = await coreUtils.fetchWithBlacklist(url, input, { fetchFn: async (requestUrl, requestInput) => fetch(requestUrl, setDispatcher(requestInput, requestUrl)), // undici.fetch }) The options object reaching undici.fetch is { ...nextRequest, agent: <pinned Node Agent>, dispatcher: <getDispatcher result> }. undici uses dispatcher and ignores agent.

The dispatcher does no IP pinningpackages/backend-core/src/utils/fetch.ts:

  • getDispatchercreateDispatcher → (no proxy env) → createDirectAgent = new Agent({ connect: { rejectUnauthorized } }) (lines ~109–114, ~161–172, ~183). This is a plain undici Agent with no connect.lookup / no pin, so undici resolves the hostname's DNS itself at connect time.

Net effect (TOCTOU / DNS rebinding): fetchWithBlacklist validates the hostname → safe public IP and builds a pinned Node agent; the REST path then connects via undici, which re-resolves the same hostname independently. With a rebinding domain (TTL 0: public IP during validation, 127.0.0.1 / 169.254.169.254 / internal IP at connect), the request lands on an internal service — exactly the gap CVE-2026-54353's pin was meant to close.

Scope of impact / why it's REST-specific: rest.ts is the only caller that overrides fetchFn with undici. All other outbound sinks (automation outgoingWebhook/n8n/make/zapier/discord/slack, and AI-extract's processUrlFile) use the default node-fetch-based fetchWithBlacklist, which does honor the pinned agent and is not affected. REST datasource queries are the most common outbound path, and the response body is returned to the caller (full-response SSRF, not blind).

PoC

The PoC drives the real, unmodified guard code (outboundFetch.ts + fetch.ts, copied verbatim — sha256 verified) and reproduces the exact rest.ts call pattern. Only the ../blacklist module is stubbed to model the rebinding input (validation observes a safe public IP). Requires Node 18+.

# prerequisite: a Budibase checkout; set BB to its path

Expected output (the port is the only variable):

[*] internal service 127.0.0.1:<random>; guard validates host -> 203.0.113.10 (safe), pins to it
(A) REST/undici path  -> status 200 body=INTERNAL_SECRET_RESPONSE
(B) node-fetch path   -> ERROR Failed to connect to resolved IP for localhost: network timeout at: http://localhost:<random>/

RESULT: PASS - undici path BYPASSES guard, node-fetch path CONTAINED

How to read it: - (A) the real fetchWithBlacklist validated and pinned the safe public IP 203.0.113.10, yet the undici REST transport re-resolved localhost and reached 127.0.0.1 — the internal service responded → SSRF bypass. - (B) the default node-fetch path honored the pin (forced to the unroutable 203.0.113.10) and never reached the internal service. The "Failed to connect to resolved IP for localhost" string is emitted by the real outboundFetch.ts, proving the pin works there. This is the negative control localizing the bug to the undici transport.

Real-world variant: instead of localhost, an attacker uses a domain they control with a 0-second TTL that returns a public IP during the guard's validation lookup and an internal IP (169.254.169.254, 127.0.0.1, internal CouchDB/Redis) at undici's connect-time lookup; the REST datasource query then returns the internal response body to the attacker.

Impact

Type: Server-Side Request Forgery via DNS rebinding (CWE-918 + CWE-367), full-response and with arbitrary HTTP method/body (REST datasources let the caller choose method, headers, and body).

Who is impacted: Any Budibase deployment on an affected version, especially multi-tenant / Budibase-Cloud-style hosting where builders/tenants are not trusted with host-internal access. The SSRF blacklist is the control that contains those users; this bypass defeats it.

Realistic worst case: An authenticated builder/tenant points a REST datasource at a rebinding host and makes the server: - read cloud metadata (http://169.254.169.254/...) → steal IAM credentials → cloud account compromise; - read the internal CouchDB (http://127.0.0.1:5984/_all_dbs, _users) → all tenants' apps, users, and secrets; - using PUT/POST/DELETE against unauthenticated localhost services → create admin documents, modify or delete tenant databases / flush caches → integrity and availability loss for all co-tenants.

CVSS 3.1 Vector Justification

Metric Value Why
Attack Vector (AV) Network (N) Triggered through Budibase's HTTP API / app (a REST datasource query).
Attack Complexity (AC) High (H) Requires DNS rebinding — the validation-time IP must differ from the connect-time IP (TOCTOU). A direct internal request without rebinding is blocked by the blacklist, so the race is mandatory.
Privileges Required (PR) Low (L) Requires an authenticated account that can configure/run a REST datasource (builder/tenant).
User Interaction (UI) None (N) The attacker configures and triggers the request; no victim interaction.
Scope (S) Changed (C) Canonical SSRF: the vulnerable component is abused to reach resources in other security authorities (cloud metadata, internal CouchDB/Redis/MinIO).
Confidentiality (C) High (H) Full-response SSRF: read cloud IAM credentials and the internal CouchDB (every tenant's apps, users, secrets).
Integrity (I) High (H) Arbitrary method/body allows PUT/POST/DELETE to unauthenticated localhost services (CouchDB :5984) → create admin docs, modify tenant data.
Availability (A) High (H) The same write primitive can DELETE databases / flush Redis → full data/service loss for all tenants.

Notes: AC:H is the standard, defensible scoring for DNS rebinding; if rebinding is treated as reliable (TTL-0 frameworks), AC:L yields CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H. A conservative read-only interpretation is I:N/A:N.

Suggested remediation

Make the transport that actually performs the request honor the validated IP. In getDispatcher/rest.ts, construct the undici Agent with a connect: { lookup } (or custom connect) that returns only the pinnedIp resolved by fetchWithBlacklist (i.e., mirror makePinnedAgent for undici), so the dispatcher cannot re-resolve DNS; alternatively, re-check the resolved peer IP against isBlacklisted inside the undici connect callback. The Node-agent pin must not be relied upon when the request is issued through undici.

  "details": "### Summary\nBudibase\u0027s central outbound-fetch guard (`fetchWithBlacklist`) prevents SSRF/DNS-rebinding by resolving the target hostname, checking every resolved IP against the blacklist, and **pinning** the connection to the validated IP. The pin is implemented as a Node `http(s).Agent` (`makePinnedAgent`). The fix for CVE-2026-54353 relies on this pin to stop DNS rebinding.\n\nThe REST datasource integration (`@budibase/server`) calls `fetchWithBlacklist` but performs the actual request with **undici**\u0027s `fetch`. undici does not support the Node `agent` option \u2014 it is silently ignored \u2014 and instead uses its own `dispatcher`, which re-resolves the hostname\u0027s DNS at connection time. As a result, **the validated/pinned IP is never used on the REST datasource path**, and the DNS-rebinding protection that CVE-2026-54353 added is silently defeated for the single most-used outbound path in Budibase.\n\nAn authenticated user who can configure/run a REST datasource (e.g. a builder/tenant) can use a rebinding hostname (public IP during validation, internal IP at connect) to make the server issue arbitrary, full-response HTTP requests to internal-only services \u2014 cloud metadata (IAM credential theft), the internal CouchDB/Redis/MinIO, and other internal endpoints \u2014 reading and, because REST datasources allow arbitrary method/body, writing or destroying internal data.\n\n\n### Details\n**The guard pins the validated IP via a Node agent** \u2014 `packages/backend-core/src/utils/outboundFetch.ts`:\n\n- `resolveSafePinnedIp(url)` resolves the hostname and checks every address against `isBlacklisted`, returning a single `pinnedIp` (lines ~39\u201353).\n- `makePinnedAgent(url, ip)` builds a **Node** `http.Agent`/`https.Agent` whose `lookup` always returns `pinnedIp`, so a node-fetch connection can only reach the validated IP (lines ~55\u201368).\n- `fetchWithBlacklist` passes that agent into the request: `fetchFn(nextUrl, { ...nextRequest, agent: makePinnedAgent(nextUrl, pinnedIp) })` (lines ~186\u2013192). Each redirect hop is re-validated and re-pinned in the loop.\n\n**The REST integration overrides the transport with undici, which ignores `agent`** \u2014 `packages/server/src/integrations/rest.ts`:\n\n- `fetch` is imported from **`undici`** (top-of-file import block, ~line 30).\n- The request is made by overriding `fetchFn` (lines ~767\u2013793):\n  ```ts\n  const setDispatcher = (requestInput, requestUrl) =\u003e ({\n    ...requestInput,\n    dispatcher: getDispatcher({ rejectUnauthorized, url: requestUrl }),\n  })\n  ...\n  response = await coreUtils.fetchWithBlacklist(url, input, {\n    fetchFn: async (requestUrl, requestInput) =\u003e\n      fetch(requestUrl, setDispatcher(requestInput, requestUrl)), // undici.fetch\n  })\n  ```\n  The options object reaching `undici.fetch` is `{ ...nextRequest, agent: \u003cpinned Node Agent\u003e, dispatcher: \u003cgetDispatcher result\u003e }`. **undici uses `dispatcher` and ignores `agent`.**\n\n**The dispatcher does no IP pinning** \u2014 `packages/backend-core/src/utils/fetch.ts`:\n\n- `getDispatcher` \u2192 `createDispatcher` \u2192 (no proxy env) \u2192 `createDirectAgent` = `new Agent({ connect: { rejectUnauthorized } })` (lines ~109\u2013114, ~161\u2013172, ~183). This is a plain undici `Agent` with **no `connect.lookup` / no pin**, so undici resolves the hostname\u0027s DNS itself at connect time.\n\n**Net effect (TOCTOU / DNS rebinding):** `fetchWithBlacklist` validates the hostname \u2192 safe public IP and builds a pinned Node agent; the REST path then connects via undici, which re-resolves the same hostname independently. With a rebinding domain (TTL 0: public IP during validation, `127.0.0.1` / `169.254.169.254` / internal IP at connect), the request lands on an internal service \u2014 exactly the gap CVE-2026-54353\u0027s pin was meant to close.\n\n**Scope of impact / why it\u0027s REST-specific:** `rest.ts` is the only caller that overrides `fetchFn` with undici. All other outbound sinks (automation `outgoingWebhook`/`n8n`/`make`/`zapier`/`discord`/`slack`, and AI-extract\u0027s `processUrlFile`) use the default node-fetch-based `fetchWithBlacklist`, which **does** honor the pinned agent and is **not** affected. REST datasource queries are the most common outbound path, and the response body is returned to the caller (full-response SSRF, not blind).\n\n### PoC\nThe PoC drives the **real, unmodified** guard code (`outboundFetch.ts` + `fetch.ts`, copied verbatim \u2014 sha256 verified) and reproduces the exact `rest.ts` call pattern. Only the `../blacklist` module is stubbed to model the rebinding **input** (validation observes a safe public IP).

The `\"Failed to connect to resolved IP for localhost\"` string is emitted by the real `outboundFetch.ts`, proving the pin works there. This is the negative control localizing the bug to the undici transport.\n\n**Real-world variant:** instead of `localhost`, an attacker uses a domain they control with a 0-second TTL that returns a public IP during the guard\u0027s validation lookup and an internal IP (`169.254.169.254`, `127.0.0.1`, internal CouchDB/Redis) at undici\u0027s connect-time lookup; the REST datasource query then returns the internal response body to the attacker.\n\n### Impact\n**Type:** Server-Side Request Forgery via DNS rebinding (CWE-918 + CWE-367), full-response and with arbitrary HTTP method/body (REST datasources let the caller choose method, headers, and body).\n\n**Who is impacted:** Any Budibase deployment on an affected version, especially multi-tenant / Budibase-Cloud-style hosting where builders/tenants are not trusted with host-internal access. The SSRF blacklist is the control that contains those users; this bypass defeats it.\n\n**Realistic worst case:** An authenticated builder/tenant points a REST datasource at a rebinding host and makes the server:\n- read cloud metadata (`http://169.254.169.254/...`) \u2192 steal IAM credentials \u2192 **cloud account compromise**;\n- read the internal CouchDB (`http://127.0.0.1:5984/_all_dbs`, `_users`) \u2192 **all tenants\u0027 apps, users, and secrets**;\n- using `PUT`/`POST`/`DELETE` against unauthenticated localhost services \u2192 create admin documents, modify or **delete** tenant databases / flush caches \u2192 integrity and availability loss for all co-tenants.\n\n### CVSS 3.1 Vector Justification\n\n| Metric | Value | Why |\n|---|---|---|\n| Attack Vector (AV) | Network (N) | Triggered through Budibase\u0027s HTTP API / app (a REST datasource query). |\n| Attack Complexity (AC) | High (H) | Requires DNS rebinding \u2014 the validation-time IP must differ from the connect-time IP (TOCTOU).

Summary
AVideo has SSRF in Scheduler Plugin via callbackURL Missing `isSSRFSafeURL()` Validation
Details

Summary

The Scheduler plugin's run() function in plugin/Scheduler/Scheduler.php calls url_get_contents() with an admin-configurable callbackURL that is validated only by isValidURL() (URL format check). Unlike other AVideo endpoints that were recently patched for SSRF (GHSA-9x67-f2v7-63rw, GHSA-h39h-7cvg-q7j6), the Scheduler's callback URL is never passed through isSSRFSafeURL(), which blocks requests to RFC-1918 private addresses, loopback, and cloud metadata endpoints. An admin can configure a scheduled task with an internal network callbackURL to perform SSRF against cloud infrastructure metadata services or internal APIs not otherwise reachable from the internet.

Details

The vulnerable code is at plugin/Scheduler/Scheduler.php:157-166:

// Line 157: callback URL retrieved and site-root token substituted
$callBackURL = $e->getCallbackURL();
$callBackURL = str_replace('$SITE_ROOT_TOKEN', $global['webSiteRootURL'], $callBackURL);
if (!isValidURL($callBackURL)) {
    return false;
}
// isValidURL() only checks URL format via filter_var(..., FILTER_VALIDATE_URL)
// The critical missing check is:
// if (!isSSRFSafeURL($callBackURL)) { return false; }
if (empty($_executeSchelude[$callBackURL])) {
    $_executeSchelude[$callBackURL] = url_get_contents($callBackURL, '', 30);

isValidURL() in objects/functions.php uses filter_var($url, FILTER_VALIDATE_URL) — it validates URL syntax only and does not block internal/private network targets.

isSSRFSafeURL() in objects/functions.php:4021 explicitly blocks: - 127.x.x.x / ::1 (loopback) - 10.x.x.x, 172.16-31.x.x, 192.168.x.x (RFC-1918 private) - 169.254.x.x (link-local, including AWS/GCP metadata at 169.254.169.254) - IPv6 private ranges

This function was added to the LiveLinks proxy (GHSA-9x67-f2v7-63rw fix, commit 0e5638292) and was previously used in the aVideoEncoder download flow (GHSA-h39h-7cvg-q7j6), but the Scheduler plugin was not updated in either fix wave, leaving it as an incomplete patch.

An admin can configure the callbackURL for a scheduled task via the Scheduler plugin UI and trigger execution immediately via the "Run now" interface.

PoC

# Step 1: Authenticate as admin

# Step 2: Create a scheduled task with cloud metadata SSRF callback
curl -b "admin_session=<session>" -X POST \
  https://target.avideo.site/plugin/Scheduler/View/Scheduler_commands/add.json.php \
  -d "callbackURL=http://169.254.169.254/latest/meta-data/iam/security-credentials/&status=a&type=&date_to_execute=2026-03-18+12:00:00"

# Step 3: Trigger immediate execution via Scheduler run endpoint
curl -b "admin_session=<session>" \
  https://target.avideo.site/plugin/Scheduler/run.php

# Step 4: Read the scheduler execution logs
curl -b "admin_session=<session>" \
  https://target.avideo.site/plugin/Scheduler/View/Scheduler_commands/get.json.php
# Response includes the AWS metadata API response with IAM role credentials

Expected: Internal network addresses rejected before HTTP request is made. Actual: The server makes an HTTP request to http://169.254.169.254/latest/meta-data/iam/security-credentials/ and the response (including AWS IAM role credentials) is stored in the scheduler execution log.

Impact

  • Cloud credential theft: On AWS, GCP, or Azure deployments, the attacker can retrieve IAM instance role credentials from the cloud metadata service (169.254.169.254), potentially enabling privilege escalation within the cloud environment.
  • Internal service probing: The attacker can make the server issue requests to internal APIs, microservices, or databases with HTTP interfaces not exposed to the internet.
  • Incomplete patch amplification: The fix for GHSA-9x67-f2v7-63rw and GHSA-h39h-7cvg-q7j6 added isSSRFSafeURL() to specific call sites but not the Scheduler. Deployments that updated expecting comprehensive SSRF protection remain vulnerable via this path.
  • Blast radius: Requires admin access. Impact is significant in cloud-hosted deployments where instance metadata credentials unlock broader infrastructure access.

Recommended Fix

Add isSSRFSafeURL() validation to the Scheduler callback URL before url_get_contents() is called, consistent with the existing SSRF fixes in plugin/LiveLinks/proxy.php and objects/aVideoEncoder.json.php:

$callBackURL = $e->getCallbackURL();
if (!isValidURL($callBackURL)) {
    return false;
}
// Add this SSRF check — same pattern as LiveLinks proxy fix (GHSA-9x67-f2v7-63rw):
if (!isSSRFSafeURL($callBackURL)) {
    _error_log("Scheduler::run SSRF protection blocked callbackURL: " . $callBackURL);
    return false;
}
if (empty($_executeSchelude[$callBackURL])) {
    $_executeSchelude[$callBackURL] = url_get_contents($callBackURL, '', 30);

Unlike other AVideo endpoints that were recently patched for SSRF (GHSA-9x67-f2v7-63rw, GHSA-h39h-7cvg-q7j6), the Scheduler\u0027s callback URL is never passed through `isSSRFSafeURL()`, which blocks requests to RFC-1918 private addresses, loopback, and cloud metadata endpoints. An admin can configure a scheduled task with an internal network `callbackURL` to perform SSRF against cloud infrastructure metadata services or internal APIs not otherwise reachable from the internet.\n\n## Details\n\nThe vulnerable code is at `plugin/Scheduler/Scheduler.php:157-166`:\n\n```php\n// Line 157: callback URL retrieved and site-root token substituted\n$callBackURL = $e-\u003egetCallbackURL();\n$callBackURL = str_replace(\u0027$SITE_ROOT_TOKEN\u0027, $global[\u0027webSiteRootURL\u0027], $callBackURL);\nif (!isValidURL($callBackURL)) {\n    return false;\n}\n// isValidURL() only checks URL format via filter_var(..., FILTER_VALIDATE_URL)\n// The critical missing check is:\n// if (!isSSRFSafeURL($callBackURL)) { return false; }\nif (empty($_executeSchelude[$callBackURL])) {\n    $_executeSchelude[$callBackURL] = url_get_contents($callBackURL, \u0027\u0027, 30);\n```\n\n`isValidURL()` in `objects/functions.php` uses `filter_var($url, FILTER_VALIDATE_URL)` \u2014 it validates URL syntax only and does not block internal/private network targets.\n\n`isSSRFSafeURL()` in `objects/functions.php:4021` explicitly blocks:\n- `127.x.x.x` / `::1` (loopback)\n- `10.x.x.x`, `172.16-31.x.x`, `192.168.x.x` (RFC-1918 private)\n- `169.254.x.x` (link-local, including AWS/GCP metadata at `169.254.169.254`)\n- IPv6 private ranges\n\nThis function was added to the LiveLinks proxy (GHSA-9x67-f2v7-63rw fix, commit `0e5638292`) and was previously used in the aVideoEncoder download flow (GHSA-h39h-7cvg-q7j6), but the Scheduler plugin was not updated in either fix wave, leaving it as an incomplete patch.\n\nAn admin can configure the `callbackURL` for a scheduled task via the Scheduler plugin UI and trigger execution immediately via the \"Run now\" interface.\n\n## PoC\n\n```bash\n# Step 1: Authenticate as admin\n\n# Step 2: Create a scheduled task with cloud metadata SSRF callback\ncurl -b \"admin_session=\u003csession\u003e\" -X POST \\\n  https://target.avideo.site/plugin/Scheduler/View/Scheduler_commands/add.json.php \\\n  -d \"callbackURL=http://169.254.169.254/latest/meta-data/iam/security-credentials/\u0026status=a\u0026type=\u0026date_to_execute=2026-03-18+12:00:00\"\n\n# Step 3: Trigger immediate execution via Scheduler run endpoint\ncurl -b \"admin_session=\u003csession\u003e\" \\\n  https://target.avideo.site/plugin/Scheduler/run.php\n\n# Step 4: Read the scheduler execution logs\ncurl -b \"admin_session=\u003csession\u003e\" \\\n  https://target.avideo.site/plugin/Scheduler/View/Scheduler_commands/get.json.php\n# Response includes the AWS metadata API response with IAM role credentials\n```\n\n**Expected:** Internal network addresses rejected before HTTP request is made.\n**Actual:** The server makes an HTTP request to `http://169.254.169.254/latest/meta-data/iam/security-credentials/` and the response (including AWS IAM role credentials) is stored in the scheduler execution log.\n\n## Impact\n\n- **Cloud credential theft:** On AWS, GCP, or Azure deployments, the attacker can retrieve IAM instance role credentials from the cloud metadata service (`169.254.169.254`), potentially enabling privilege escalation within the cloud environment.\n- **Internal service probing:** The attacker can make the server issue requests to internal APIs, microservices, or databases with HTTP interfaces not exposed to the internet.\n- **Incomplete patch amplification:** The fix for GHSA-9x67-f2v7-63rw and GHSA-h39h-7cvg-q7j6 added `isSSRFSafeURL()` to specific call sites but not the Scheduler. Deployments that updated expecting comprehensive SSRF protection remain vulnerable via this path.\n- **Blast radius:** Requires admin access. Impact is significant in cloud-hosted deployments where instance metadata credentials unlock broader infrastructure access.\n\n## Recommended Fix\n\nAdd `isSSRFSafeURL()` validation to the Scheduler callback URL before `url_get_contents()` is called, consistent with the existing SSRF fixes in `plugin/LiveLinks/proxy.php` and `objects/aVideoEncoder.json.php`:\n\n```php\n$callBackURL = $e-\u003egetCallbackURL();\nif (!isValidURL($callBackURL)) {\n    return false;\n}\n// Add this SSRF check \u2014 same pattern as LiveLinks proxy fix (GHSA-9x67-f2v7-63rw):\nif (!isSSRFSafeURL($callBackURL)) {\n    _error_log(\"Scheduler::run SSRF protection blocked callbackURL: \" . $callBackURL);\n    return false;\n}\nif (empty($_executeSchelude[$callBackURL])) {\n    $_executeSchelude[$callBackURL] = url_get_contents($callBackURL, \u0027\u0027, 30);\n```",

CAPEC-664: Server Side Request Forgery

An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
