Summary
WWBN AVideo versions 26.0 and prior have an SSRF vulnerability in the EPG (Electronic Program Guide) feature. Authenticated users with upload permissions can store arbitrary URLs that the server fetches on every EPG page visit. Insufficient URL validation allows scanning internal networks and accessing internal services.
Risk Assessment
The SSRF vulnerability allows an attacker to scan internal networks, access cloud metadata, and interact with internal services, potentially leading to data leakage or further attacks.
Recommendation
Apply temporary mitigations such as blocking internal addresses in the EPG feature and wait for an official patch from the vendor.
Original NVD description (English source)
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.
