Description
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.
Analysis
Stored server-side request forgery (SSRF) in WWBN AVideo 26.0 and prior allows authenticated users with upload permissions to inject arbitrary URLs into the EPG (Electronic Program Guide) link feature, which the server automatically fetches on each EPG page visit. This enables attackers to scan internal networks, access cloud metadata services, and interact with internal services without the authentication or complexity barriers normally present in network-based attacks. …
