AVideo before 29.1.0 contains a stored cross-site scripting vulnerability in the video trailer1 field rendered unsanitized within an inline onclick JavaScript string. Attackers with video upload permission can store HTML entity-encoded payloads that bypass isValidURL() validation and are decoded by the browser to break out of the JavaScript string, executing arbitrary code in any visitor's session including administrators.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
