ClipBucket < 5.5.3-#182 Blind SQL Injection via Private Message Deletion Endpoint
CVSS Score
6.5

0.0%
EPSS Percentile
0th
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.
