Detailsinfo

A vulnerability, which was classified as critical, has been found in WWBN AVideo up to 25.x. This issue affects the function url_get_contents of the file plugin/BulkEmbed/save.json.php of the component HTTP Request Handler. The manipulation with an unknown input leads to a server-side request forgery vulnerability. Using CWE to declare the problem leads to CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

WWBN AVideo is an open source video platform. Prior to version 26.0, the BulkEmbed plugin's save endpoint (`plugin/BulkEmbed/save.json.php`) fetches user-supplied thumbnail URLs via `url_get_contents()` without SSRF protection. Unlike all six other URL-fetching endpoints in AVideo that were hardened with `isSSRFSafeURL()`, this code path was missed. An authenticated attacker can force the server to make HTTP requests to internal network resources and retrieve the responses by viewing the saved video thumbnail. Version 26.0 fixes the issue.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-33294 since 03/18/2026. The exploitation is known to be easy. The attack may be initiated remotely. Technical details are known, but no exploit is available.
