What is CVE-2026-77927?
CVE-2026-77927 is a high-severity SQL injection vulnerability in MacWarrior clipbucket-v5, published on 18 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-89
