Frequently Asked Questions
1
Who can exploit this issue?
Remote authenticated users who can upload subtitles can supply a crafted subtitle filename. The payload is stored and can execute later when the deletion flow renders that filename.
2
When is a user exposed to the stored payload?
Exposure occurs when the crafted subtitle filename is rendered at /subtitles.php?action=delete. Users accessing that deletion flow for the affected subtitle may execute the injected JavaScript.
