Description

ClipBucket v5 is an open source video sharing platform. An authenticated time-based blind SQL injection vulnerability exists in ClipBucket prior to 5.5.3 #80 within the `actions/ajax.php` endpoint. Due to insufficient input sanitization of the `userid` parameter, an authenticated attacker can execute arbitrary SQL queries, leading to full database disclosure and potential administrative account takeover. Version 5.5.3 #80 fixes the issue.
