Vulnerability from github – Published: 2026-09-16 18:32 – Updated: 2026-09-16 18:32

Details

Guns through 8.3.5 contains an information disclosure vulnerability in SysUserController where /sysUser/detail and /sysUser/page endpoints omit requiredPermission configuration, causing the permission interceptor to skip RBAC validation for authenticated users. Attackers with any valid login token can retrieve sensitive user information including account names, real names, email addresses, phone numbers, last login IPs, and role assignments for all users in the system.

Severity

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
