CVE-2026-33766 Details
Description
WWBN AVideo is an open source video platform. In versions up to and including 26.0, `isSSRFSafeURL()` validates URLs against private/reserved IP ranges before fetching, but `url_get_contents()` follows HTTP redirects without re-validating the redirect target. An attacker can bypass SSRF protection by redirecting from a public URL to an internal target. Commit 8b7e9dad359d5fac69e0cbbb370250e0b284bc12 contains a patch.
A server-side request forgery (SSRF) vulnerability has been identified in WWBN AVideo versions through 26.0. The issue arises because the function 'isSSRFSafeURL()' correctly validates URLs against private and reserved IP ranges before fetching. However, the 'url_get_contents()' function follows HTTP redirects without re-validating the target URL. This flaw allows an attacker to bypass SSRF protections by redirecting from a public URL to an internal one. The vulnerability has been patched by disabling automatic HTTP redirects and manually handling them with proper validation.
Users can update to the latest version of WWBN AVideo, where this vulnerability has been addressed. Instructions for updating can be found in the AVideo documentation.
