Prior to 16.4.0, admin/batch_manager.php accepts administrator-controlled dimension width, height, and ratio values and filesize values from the Batch Manager filter URL without numeric validation. The URL filter parser stores those values in the bulk_manager_filter session state, and later query construction concatenates them into SQL predicates, unlike the validated POST filter path. An authenticated administrator can use crafted filter values to execute time-based or other SQL expressions and potentially disclose, modify, or disrupt database data. This issue is fixed in version 16.4.0.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":52,"depthScoreParts":{"impact":39.6,"likelihood":0.2,"exploitation":12,"ransomware":0},"changes":[{"seq":211982,"id":"CVE-2026-42323","ts":1790608491767,"field":"exploit_available","old":"false","new":"true"}]}
