CVE-2026-34970 Details
Description
Mantis Bug Tracker (MantisBT) is an open source issue tracker. Versions 2.28.1 and prior allow a bugnote author to access the note's Revisions page after losing access to the parent private issue. This issue has been fixed in version 2.28.2.
A vulnerability in Mantis Bug Tracker (MantisBT) versions through 2.28.1 allows bugnote authors to access the Revisions page of their notes after losing access to the parent private issue. This access reveals metadata from the private issue, such as the issue ID and summary, while the full revision body remains secure. The vulnerability arises because the access control for bugnote revisions does not properly check if the user can view the associated private issue.
Users can upgrade to MantisBT version 2.28.2, where this vulnerability has been fixed.
