GHSA-C94R-CGJW-F264
Vulnerability from github – Published: 2026-09-27 03:31 – Updated: 2026-09-27 03:31AzuraCast is a self-hosted web radio management suite. In AzuraCast before 0.23.8, the station webhook URL validation in AbstractConnector::getValidUrl() (backend/src/Webhook/Connector/AbstractConnector.php), used by the Generic and Discord webhook connectors, rejects only URLs whose host is a literal link-local IP address (169.254.0.0/16 or fe80::/10). Loopback addresses and RFC1918 private ranges are not rejected, and any non-literal-IP hostname causes the IP parsing call to throw, which skips the check entirely. A user holding only the station-scoped WebHooks permission can therefore configure a webhook pointing at an internal, loopback, or private-network target and cause the server to issue an outbound HTTP POST containing the station's Now Playing data, resulting in server-side request forgery. The PUT /station/{id}/webhook/{id}/test endpoint allows the same low-privileged user to trigger the request on demand. At the time of the advisory no patched version was available.

GHSA-C9HR-64H3-GXPC
Vulnerability from github – Published: 2026-07-30 14:48 – Updated: 2026-07-30 14:48Summary
The HTTP modules that DO call the SSRF guard (http.get, http.request, http.batch) validate only the initial URL, then issue the request with aiohttp's default allow_redirects=True and perform no per-hop revalidation. An attacker hosts a public URL that 302-redirects to an internal address; the guard passes on the public host and aiohttp transparently follows the redirect into internal space, returning the internal body.
Root Cause
src/core/modules/atomic/http/get.py:116 calls session.get(url, ...) with no allow_redirects argument → aiohttp default True. request.py:60 sets allow_redirects=follow_redirects (default True at :327); batch.py:57 likewise. A repo grep of http/ for on_request_redirect / response.history returns NONE — there is no redirect interception or Location revalidation.
Impact
Full readable SSRF that defeats the primary SSRF control on the very modules that correctly validate. Confidentiality of internal/metadata responses (C:H), S:C.
Proof of Concept
Verified live: http.get with allowlisted base 127.0.0.1 followed a 302 Location: http://127.0.0.2/... (non-allowlisted) and returned INTERNAL-VIA-REDIRECT.
attacker hosts http://attacker.tld/r -> 302 Location: http://<cloud-metadata-ip>/latest/meta-data/...
execute_module http.get {"url":"http://attacker.tld/r"}
Attack Chain
- Entry:
execute_module http.get {url:"http://attacker.tld/r"}(attacker 302->internal). Guard:validate_url_with_env_config(url)(get.py:104). Bypass proof: validation runs onattacker.tld(public) → passes; never re-run on the redirect target. - Sink:
session.get(url)(get.py:116) — noallow_redirectsarg → aiohttp default True. Bypass proof: grep ofhttp/foron_request_redirect/response.history→ NONE. - Impact: aiohttp follows 302 to the internal host; internal body returned (get.py:118).
Bypass Evidence
Live PoC followed a 302 into non-allowlisted loopback and returned the internal marker string. aiohttp ClientSession.get default allow_redirects=True; module never sets it False; no per-hop revalidation exists.
Affected Versions
<= 2.26.6 — get.py:116, request.py:60, batch.py:57 present on latest release tag.
Suggested Fix
Set allow_redirects=False and manually revalidate each Location header through validate_url_with_env_config before following, or cap and re-check every hop.

GHSA-C9JJ-9W3R-2HJ8
Vulnerability from github – Published: 2026-09-26 15:31 – Updated: 2026-09-26 15:31Adminer 4.16.0 through 6.0.1 contain a pre-authentication Server-Side Request Forgery (SSRF) vulnerability in the optional Elasticsearch driver (plugins/drivers/elastic.php), fixed in 6.0.2. Because adminer/include/auth.inc.php invokes Driver::connect() before the login result is validated, an unauthenticated attacker who submits crafted auth[server], auth[username], and auth[password] parameters can cause the Adminer server to issue an HTTP GET request (via get_url()/file_get_contents()) to an arbitrary reachable host and port. The driver validates only general server syntax and does not block loopback, private, link-local, or other reserved addresses; if no port is given it appends the default 9200, and Adminer's generic port check rejects ports below 1024. Selected JSON error fields from non-2xx Elasticsearch-style responses, as well as connection failures, are rendered on the login page, providing a port-scanning oracle and enabling internal network reconnaissance and service fingerprinting. Exploitation requires that the optional Elasticsearch driver be explicitly deployed (e.g., via the adminer/elastic.php template or an adminer_object() configuration; it is not loaded in a default build) and that PHP allow_url_fopen be enabled.

GHSA-CCCC-WRRH-HW2H
Vulnerability from github – Published: 2026-08-20 00:35 – Updated: 2026-08-20 00:35In Cisco Talos Intelligence for Enterprise Security Cloud versions below 1.0.3, a user that holds a role with the get_talos_enrichment capability could send a crafted request to the Talos intelligence enrichment Representational State Transfer (REST) API endpoint and cause the instance to make an outbound request to an attacker-controlled server. The request could expose tokens that compromise all relevant data and system integrity in the Splunk instance. The vulnerability is possible because the Talos intelligence enrichment REST endpoint accepts the destination for authenticated Splunk management requests from request data. For more information see Deploy Cisco Talos Intelligence for Splunk Enterprise Security (https://help.splunk.com/en/splunk-enterprise-security-8/user-guide/8.0/introduction/deploy-cisco-talos-intelligence-for-splunk-enterprise-security-cloud-only) in the Splunk documentation.

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.
