Official 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.
Technical Analysis
CVE-2026-32321 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
From a weakness classification perspective (CWE-89): SQL injection vulnerabilities allow attackers to manipulate database queries, potentially exposing or modifying sensitive data.
