AVideo video trailer can run code in browsers

CVE-2026-105089 · published 14 days ago
Summary

That link is shown on pages without proper safety checks, so when other users view the page the hidden code runs in their browser. Restrict who can upload videos and apply the latest update that fixes the issue.
