What is CVE-2026-108643?

JeecgBoot version 3.9.5 is susceptible to a missing authorization issue, allowing authenticated users with low privileges to delete category dictionary entries improperly. By exploiting this vulnerability, an attacker can leverage the unprotected rootList and childList endpoints to retrieve node IDs. This enables them to send requests for recursive deletion of entire sys_category subtrees, potentially disrupting dependent forms and dictionary fields. As a result, this could lead to significant data loss and system integrity issues.

Affected Version(s)

JeecgBoot 0 <= 3.9.5
