CVE-2026-55072
Published:August 13, 2026
Updated:August 27, 2026
A missing end anchor ("$") in the ClassDefinition UID validation regex allows an authenticated user with the "objects" permission to create a class with a malicious UID containing SQL. When a data object of that class is later loaded, Block.php concatenates the raw classId directly into a SQL query without quoting, executing the injected payload. This is an incomplete fix from commit "dbe1d131e4" which added a leading "^" anchor but omitted the trailing "$".
