CVE-2026-77928 Details
Description
ClipBucket v5 before 5.5.3-#182 contains a blind SQL injection vulnerability that allows authenticated users to extract arbitrary database contents by submitting the msg_id parameter as an array to bypass the clean_requests() sanitization function in ClipBucket.class.php. Attackers can pass unsanitized array elements through the deletion handler in private_message.php into cb_pm::delete_msg(), which interpolates the unescaped message ID directly into a SQL query string, enabling time-based blind SQL injection to retrieve all user credential hashes and email addresses.
A blind SQL injection vulnerability has been identified in ClipBucket versions 5 prior to 5.5.3-#182. This vulnerability allows authenticated users to extract arbitrary data from the database. The issue arises in the private_message.php file, specifically within the cb_pm::delete_msg() function, which directly incorporates the message ID into a SQL query without proper sanitization. Exploitation involves sending the msg_id parameter as an array to bypass the clean_requests() function, enabling attackers to execute time-based SQL injection and retrieve user credential hashes and email addresses.
Users are advised to update to ClipBucket version 5.5.3-#182 or later, where this vulnerability has been fixed.
