JeecgBoot Missing Authorization in SysCategoryController

Publication date: 2026-10-10

Last updated on: 2026-10-10

Assigner: VulnCheck

Description

JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysCategoryController delete handler that allows any authenticated user to delete category dictionary nodes. Low-privileged attackers can obtain node ids from the unguarded rootList and childList endpoints and delete entire sys_category subtrees, breaking dependent forms and dictionary fields.

Attack-Flow Graph

Executive Summary

JeecgBoot through version 3.9.5 has a missing authorization vulnerability in the SysCategoryController delete handler. This allows any authenticated user, even with low privileges, to delete category dictionary nodes by obtaining node IDs from unprotected endpoints like rootList and childList. Attackers can delete entire sys_category subtrees, which breaks dependent forms and dictionary fields.

Detection Guidance

Check for unauthorized deletions in JeecgBoot logs or database. Monitor sys_category table changes and inspect API calls to /sysCategory/delete. Look for requests with valid node IDs obtained from unprotected /rootList or /childList endpoints.

Impact Analysis

Low-privileged attackers could exploit this to delete critical category nodes, disrupting system functionality. This may cause data integrity issues, break dependent forms, and corrupt dictionary fields, leading to application failures or incorrect data handling.

Compliance Impact

This vulnerability allows low-privileged attackers to delete critical category dictionary nodes, which could break dependent forms and dictionary fields. This may lead to data integrity issues, unauthorized data modification, or loss of audit trails, potentially violating compliance requirements for data accuracy and protection under standards like GDPR and HIPAA.

Mitigation Strategies

Upgrade JeecgBoot to version 3.9.6 or later. Implement strict access controls for /sysCategoryController endpoints. Disable unprotected /rootList and /childList endpoints. Review and restrict user permissions to prevent unauthorized deletions.
