### Vulnerability Type Authenticated Server-Side Request Forgery (SSRF) ### Affected Product/Versions AVideo versions prior to 22 (tested on AVideo 21.x). ### Root Cause Summary 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). ### Impact Summary 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. ### Resolution/Fix This issue has been fixed in AVideo version 22. Users should upgrade to version 22.0 as soon as possible. ### Credits/Acknowledgement Thanks to Arkadiusz Marta for responsibly reporting this issue. - GitHub Profile: https://github.com/arkmarta/

WWBN AVideo is an open source video platform. Prior to version 21.0, AVideo allows Markdown in video comments and uses Parsedown (v1.7.4) without Safe Mode enabled. Markdown links are not sufficiently sanitized, allowing `javascript:` URIs to be rendered as clickable links. An authenticated low-privilege attacker can post a malicious comment that injects persistent JavaScript. When another user clicks the link, the attacker can perform actions such as session hijacking, privilege escalation (including admin takeover), and data exfiltration. Version 21.0 contains a fix. As a workaround, validate and block unsafe URI schemes (e.g., `javascript:`) before rendering Markdown, and enable Parsedown Safe Mode.
