description

AVideo versions at least 14.3 through v29.7.1 and current master are affected by stored cross-site scripting in the video-manager tag display. An authenticated account with video-upload permission can store content through the encoder endpoint that executes in an administrator's or video moderator's browser when they view the video manager.

Still under analysis: more detail becomes available as the pipeline runs.

mitigation

Block or reject JSON request bodies to objects/aVideoEncoder.json.php at the reverse proxy, and limit upload permission to trusted users until a vendor update is available. Apply local input validation for JSON-decoded fields and HTML-escape tag values before rendering them.
