CVE-2026-105086

critical · 9.3

WWBN AVideo 12.4 through 29.2.0 contains a stored cross-site scripting vulnerability that allows authenticated uploaders to inject HTML by submitting doubly-encoded entities in video titles. Because safeString() strips tags before decoding entities and runs twice via setTitle() and save(), attackers can store markup that executes in trending, gallery, embed, and playlist pages.
