Alert meAnalysisAIv1 – Mar 12, 2026
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.
Earlier versions of this analysis (1)
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. [CVSS 8.1 HIGH]
RemediationAI
A vendor patch is available — apply it immediately. Restrict network access to the affected service where possible.

2DescriptionGitHub Advisory
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.
Executive ViewAI
WWBN AVideo installations prior to version 22.0 contain a server-side request forgery (SSRF) vulnerability that could allow attackers to access internal resources, exfiltrate data, or pivot to backend systems. Any organization running this open-source video platform on affected versions faces potential data compromise and lateral movement risks from both external and internal threat actors.
Apply vendor patch. If immediate patching is delayed: (1) Restrict network access to aVideoEncoder.json.php endpoint using WAF rules or IP whitelisting; (2) Implement egress filtering to block unexpected outbound connections from the application server; (3) Disable the encoder feature if not actively used; (4) Segment the video platform from sensitive internal systems.
