What is CVE-2025-64339?

ClipBucket, an open-source video sharing platform, suffers from a stored Cross-Site Scripting (XSS) vulnerability affecting versions v5.5.2-#146 and below. The flaw exists within the 'Manage Playlists' feature, where an authenticated low-privileged user can create playlists with malicious names that include HTML/JavaScript code. When these playlists are displayed on detail and listing pages, the code is executed without escaping, potentially allowing attackers to execute arbitrary JavaScript in the browsers of all viewers, including administrators. This issue has been addressed in version 5.5.2-#147, making it essential for users to update.
