## Technical details

An Insecure Direct Object Reference (IDOR) vulnerability exists in the JobLogController.java component of XXL-JOB. The 'logDetailCat' endpoint fails to implement the 'validJobGroupPermission' check used by its sibling endpoint 'logDetailPage'. An authenticated attacker can exploit this by providing incremented 'logId' parameters to the endpoint, allowing them to enumerate and retrieve sensitive execution logs across all job groups regardless of their assigned permissions. The vulnerability is confirmed in version 2.4.2 and the current master branch (commit 71530be).
