Summary

CVE-2026-41060 is a high-severity SSRF (CWE-918) vulnerability in Wwbn Avideo. Its CVSS base score is 7.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-4 (Information Flow Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-41060 is a server-side request forgery (SSRF) vulnerability in WWBN AVideo, an open-source video platform, affecting versions 29.0 and below. The flaw exists in the `isSSRFSafeURL()` function in `objects/functions.php` at lines 4290-4296, where a same-domain shortcut compares only the hostname against `webSiteRootURL`, ignoring the port number. This bypasses all SSRF protections for URLs sharing the site's hostname but targeting arbitrary ports on the server.

The vulnerability requires low privileges (PR:L) and network access (AV:N) for exploitation, with no user interaction needed (UI:N). An attacker can craft a URL using the site's public hostname with a non-standard port to access internal services on the AVideo server. The response body is then saved to a web-accessible path, allowing complete exfiltration of sensitive data. It carries a CVSS v3.1 base score of 7.7 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N) and maps to CWE-918 (Server-Side Request Forgery).

The official patch is provided in commit a0156a6398362086390d949190f9d52a823000ba on the AVideo GitHub repository, which fixes the port omission in the safety check. The GitHub security advisory GHSA-j432-4w3j-3w8j recommends applying this commit to mitigate the issue.

Vulnerability Data

WWBN AVideo is an open source video platform. In versions 29.0 and below, the `isSSRFSafeURL()` function in `objects/functions.php` contains a same-domain shortcircuit (lines 4290-4296) that allows any URL whose hostname matches `webSiteRootURL` to bypass all SSRF protections. Because the check…

compares only the hostname and ignores the port, an attacker can reach arbitrary ports on the AVideo server by using the site's public hostname with a non-standard port. The response body is saved to a web-accessible path, enabling full exfiltration. Commit a0156a6398362086390d949190f9d52a823000ba fixes the issue.

Mitigating Controls (NIST 800-53 r5) AI

Information flow enforcement can restrict which destinations the server is allowed to contact on behalf of users.

Input validation directly stops untrusted URLs from being accepted and fetched without destination checks.

Boundary protection limits the network reach of server-initiated requests even if SSRF occurs.
