CVE-2026-106991 Details
Description
hustoj >=24.09.10 and <=26.08.19 is vulnerable to Incorrect Access Control. Any registered user can delete, lock, or sticky any forum thread (including admins' announcements) via threadadmin.php. The thread branch only verifies login, never authorship or admin rights.
A vulnerability in Hustoj versions 24.09.10 through 26.08.19 allows registered users to manipulate forum threads without proper authorization. The issue arises in the thread administration endpoint, threadadmin.php, which only verifies if a user is logged in, but fails to check if they are the thread author or have administrative rights. As a result, any logged-in user can delete, lock, or pin any thread, including important announcements from administrators.
Users can update to Hustoj version 26.09.12 or later, where this vulnerability has been fixed. Instructions for updating are available in the Hustoj repository.
