CVE-2025-55155
MantisBT: Authentication bypass for some passwords due to PHP type juggling
Description

Mantis Bug Tracker (MantisBT) is an open source issue tracker. In versions 2.27.1 and below, when a user edits their profile to change their e-mail address, the system saves it without validating that it actually belongs to the user. This could result in storing an invalid email address, preventing the user from receiving system notifications. Notifications sent to another person's email address could lead to information disclosure. This issue is fixed in version 2.27.2.
