CVE-2026-65316Public exploitNetwork attack vector

Authenticated log disclosure via missing group authorization

Published Jul 21, 2026 · Updated Jul 21, 2026

Insecure direct object reference in XXL-JOB 2.4.2 allows remote authenticated users to read restricted job-group logs by log ID. JobLogController.logDetailCat loads a caller-supplied sequential logId and proxies the log body without invoking JobGroupPermissionUtil.validJobGroupPermission for the record's group. Any logged-in non-admin account can enumerate IDs and disclose executor parameters, internal addresses, stack traces, and other content written to logs outside its assigned groups.
