CVE-2026-105086
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
