WWBN AVideo is an open source video platform. Prior to version 22.0, the aVideoEncoder.json.php API endpoint accepts a downloadURL parameter and fetches the referenced resource server-side without proper validation or an allow-list. This allows authenticated users to trigger server-side requests to arbitrary URLs (including internal network endpoints). An authenticated attacker can leverage SSRF to interact with internal services and retrieve sensitive data (e.g., internal APIs, metadata services), potentially leading to further compromise depending on the deployment environment. This issue has been fixed in AVideo version 22.0.
AnalysisAI
Server-side request forgery in AVideo prior to version 22.0 allows authenticated users to make arbitrary outbound requests from the affected server via an unvalidated downloadURL parameter in the aVideoEncoder.json.php endpoint. An attacker can exploit this to probe internal network services, access metadata endpoints, and retrieve sensitive data, potentially leading to further system compromise. This affects PHP deployments running vulnerable AVideo versions.
