SCA: security update for wwbn/avideo (GHSA-rcqw-6466-3mv7)
medium Tenable Self-Hosted Container Security Plugin ID 437920
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- 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.
