Detailsinfo

A vulnerability was found in WWBN AVideo up to 26.0. It has been classified as critical. Affected is the function isSSRFSafeURL of the component EPG Page. The manipulation with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

WWBN AVideo is an open source video platform. In versions 26.0 and prior, the EPG (Electronic Program Guide) link feature in AVideo allows authenticated users with upload permissions to store arbitrary URLs that the server fetches on every EPG page visit. The URL is validated only with PHP's FILTER_VALIDATE_URL, which accepts internal network addresses. Although AVideo has a dedicated isSSRFSafeURL() function for preventing SSRF, it is not called in this code path. This results in a stored server-side request forgery vulnerability that can be used to scan internal networks, access cloud metadata services, and interact with internal services. At time of publication, there are no publicly available patches.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-34740 since 03/30/2026. The exploitability is told to be easy.
