CVE-2026-108623 · Severity: high · CVSS 7.1 · Published 2026-10-10

JeecgBoot is an enterprise application development platform. Authenticated attackers can delete system audit logs without proper permission checks, allowing them to erase all evidence of their actions or other users' activities on the system. An attacker can send a specially crafted delete request to wipe the entire audit log table, destroying the audit trail critical for compliance and forensics.

## Technical details

The SysLogController.deleteBatch() method at lines 125-140 lacks the @RequiresPermissions annotation (it is commented out), allowing any authenticated user to invoke the handler. The vulnerability exists in the DELETE /sys/log/deleteBatch endpoint; when the ids parameter is set to "allclear", the handler calls removeAll() which executes an unbounded DELETE FROM sys_log statement. An authenticated attacker gains the ability to perform administrative audit log deletion without authorization checks.
