Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

MantisBT versions before 2.27.2 save a user's changed email address without checking that it belongs to that user. An account holder can therefore store an address they do not control, so the user stops receiving system notifications and notifications may go to someone else, leading to information disclosure. Upgrade to MantisBT 2.27.2, which fixes the issue. No workaround is listed.
