Summary
WWBN AVideo 29.1.0 through 29.7.1 contains a stored cross-site scripting vulnerability that allows registered users to inject markup through the channel About field rendered in feed/index.php. Attackers can store an unquoted event-handler payload that bypasses feedHtmlDescription() filtering and executes via rss-style.xsl for any visitor, including administrators, viewing the channel feed.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
The maintainers of WWBN/AVideo published their own advisory on GitHub. Reviewed sources take precedence over it.
