SQL Injection in Macwarrior Clipbucket-V5
CVE-2026-77927
ClipBucket v5 before 5.5.3-#182 contains a blind SQL injection vulnerability that allows authenticated users to extract arbitrary data from the database by submitting the check_photo parameter as an array to bypass the clean_requests() sanitization function in ClipBucket.class.php. Attackers can pass unsanitized array elements through the bulk deletion handler in manage_photos.php to photo_exists() in photos.class.php, where non-numeric values are interpolated directly into a SQL query, enabling time-based blind SQL injection to retrieve credential hashes and other sensitive data.
