CVE-2026-116139
Published:October 25, 2026
Updated:November 12, 2026
WWBN AVideo 26.0 through 29.3.0 contains a stored cross-site scripting vulnerability that allows authenticated commenters to inject JavaScript because markDownToHTML() preserves event-handler attributes in leading HTML blocks. Attackers can post a comment starting with an img tag carrying an onerror handler, which bypasses the inline sanitizer and executes in viewers' browsers under the application origin.
