Summary

A stored XSS vulnerability in AVideo (Meet plugin) allows an attacker to inject malicious JavaScript via the User-Agent header when joining a public meeting. The payload is stored and later executed in the admin or host's browser session when viewing the participant list.

Risk Assessment

An attacker can hijack the session of an administrator or meeting host, steal credentials, or perform unauthorized actions within the AVideo application.

Recommendation

Immediately update the Meet plugin to the latest version or apply a temporary fix by sanitizing and encoding the User-Agent header output in getMeetInfo.json.php.

Original NVD description (English source)

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.
