CVE-2026-42070 · MantisBT: Authorization Bypass in Bugnote Editing via Issue Update API

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Mantis Bug Tracker (MantisBT) is an open source issue tracker. Prior to 2.28.2, the mc_issue_update() function in MantisBT allows users having update_bug_threshold access (UPDATER, with default settings) to edit, change view state, and modify time tracking on bugnotes belonging to other users — bypassing the default DEVELOPER (level 55) threshold required by the dedicated mc_issue_note_update() function. This vulnerability is fixed in 2.28.2.
