Password-hash disclosure via unsanitized username-update response
Published Nov 6, 2023 · Updated Sep 12, 2024
Information disclosure in Mattermost 9.0.0 and earlier allows remote authenticated users to obtain a password hash through a username update. The username-update path returns the updated user object without applying the response sanitization that removes the stored password hash. Administrative privileges are required, and the reported consequence is limited to disclosure of the returned hash.
