Key facts

Description

AVideo (Meet plugin) through commit e8d6119f3cb1b849149906efeb0a41fc024f59f8 contains a stored cross-site scripting vulnerability in the Meet plugin's getMeetInfo.json.php endpoint. When a participant joins a public meeting, the raw HTTP User-Agent header is stored (meet_join_log.user_agent) without sanitization (bypassing AVideo's setter-level xss_esc() layer) and later echoed without output encoding (no htmlspecialchars()) in the Participants management panel, which is accessible to the meeting host and site administrators. An anonymous, unauthenticated attacker can join any public meeting while supplying a User-Agent header containing an HTML/JavaScript payload; the payload is persisted and executes in the privileged, authenticated browser session of the meeting host or a site administrator when they open the participant list. The issue was unpatched at the time of the report.
