Unauthenticated code execution via H2 SQL injection
Published Apr 7, 2026 · Updated Apr 7, 2026
SQL injection in PowerJob 5.1.0 through 5.1.2 allows remote attackers to execute commands through the unauthenticated detailPlus endpoint. InstanceController passes customQuery through a keyword blacklist, and TaskDAOImpl concatenates the surviving value into an H2 WHERE clause. Code execution requires a running broadcast job so the worker processes customQuery; H2 RUNSCRIPT can load attacker-hosted SQL that creates and invokes an alias.
