## What is CVE-2025-55155?

CVE-2025-55155 is a medium-severity vulnerability in Mantisbt Mantisbt, published on 4 Nov 2025. Any signed-in user can exploit it over the network, with no action from the victim.

### Official 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.

Weakness: CWE-354 (Improper Validation of Integrity Check Value), CWE-201 (Insertion of Sensitive Information Into Sent Data)
