CVE-2026-42070
Published:May 28, 2026
Updated:June 13, 2026
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.
