CVE-2026-65316

xuxueli xxl-jobVulnerabilityCVSS 7.1

XXL-Job version 2.4.2 contains an insecure direct object reference vulnerability that allows authenticated users to read execution log content from job groups they are not authorized to access by supplying arbitrary sequential log IDs to the logDetailCat endpoint. Attackers can enumerate log records across all job groups by calling the logDetailCat endpoint with incremented logId parameter values, bypassing the permission check present in the sibling logDetailPage endpoint, and retrieve sensitive log content from restricted job groups.

No public exploitation has been reported so far. No distribution fix is listed yet; apply vendor mitigations and monitor.

Recommended action: Track your distribution's security tracker and apply the fix as soon as it ships.

Affected & fixed versions by distribution

Versions are the native distribution strings (backport-aware): RHEL/Debian/SUSE backport fixes, so compare with the distro version comparator (dpkg / rpm / vercmp), not the upstream version.

No affected package in the tracked watchlist yet (Debian, Ubuntu, Arch, SUSE, Red Hat...). Triage may still be pending.
