Vulnerability from github – Published: 2026-03-05 20:42 – Updated: 2026-03-06 15:17

Summary

Gokapi has privilege escalation via incomplete API-key permission revocation on user rank demotion

Details

Summary

A privilege escalation vulnerability in the user rank demotion logic allows a demoted user's existing API keys to retain ApiPermManageFileRequests and ApiPermManageLogs permissions, enabling continued access to upload-request management and log viewing endpoints after the user has been stripped of all privileges.

Impact

Any user who previously held Admin rank and had API keys with ApiPermManageFileRequests or ApiPermManageLogs retains those capabilities after demotion. This allows offboarded or demoted users to: - Create, list, and delete upload requests - Read application logs and system status

Severity

5.4 (Medium)

Vulnerability from cvelistv5 – Published: 2026-03-06 04:45 – Updated: 2026-03-06 16:06

Title

Gokapi: Privilege escalation via incomplete API-key permission revocation on user rank demotion

Summary

Gokapi is a self-hosted file sharing server with automatic expiration and encryption support. Prior to version 2.2.3, a privilege escalation vulnerability in the user rank demotion logic allows a demoted user's existing API keys to retain ApiPermManageFileRequests and ApiPermManageLogs permissions, enabling continued access to upload-request management and log viewing endpoints after the user has been stripped of all privileges. This issue has been patched in version 2.2.3.

Severity

5.4 (Medium)
