What is CVE-2026-103766?

ClipBucket versions 5 through 5.5.3-#197 are susceptible to an SQL injection vulnerability that potentially allows authenticated users with ad_manager_access permission to manipulate SQL queries via the delete parameter in admin_area/ads_manager.php. By leveraging time-based blind payloads, attackers can extract sensitive user information, such as credentials and emails, or maliciously alter and remove records within the database. Prompt application of security patches and best practices are essential to mitigate exploitation risks.
