Unknown · Clipbucket · CVE-2026-21875
**Name of the Vulnerable Software and Affected Versions**
ClipBucket versions 5.5.2 through 5.5.2-#187
**Description**
ClipBucket v5 is a video sharing platform susceptible to a Blind SQL Injection issue. The flaw exists within the add comment section of a channel. An attacker can exploit this by sending a POST request to the `/actions/ajax.php` endpoint. The `obj id` parameter within this request is used in the `user exists` function of the `upload/includes/classes/user.class.php` file, specifically as the `$id` parameter. This `$id` parameter is then used in the `count` function of the `upload/includes/classes/db.class.php` file. The parameter is incorporated into a query without proper validation or sanitization, allowing a crafted input like `1' or 1=1-- -` to trigger the injection.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
