WWBN AVideo is an open source video platform. In versions up to and including 26.0, a sanitization order-of-operations flaw in the user profile "about" field allows any registered user to inject arbitrary JavaScript that executes when other users visit their channel page. The `xss_esc()` function entity-encodes input before `strip_specific_tags()` can match dangerous HTML tags, and `html_entity_decode()` on output reverses the encoding, restoring the raw malicious HTML. Commit 7cfdc380dae1e56bbb5de581470d9e9957445df0 contains a patch.
