Message disclosure via unsanitized audit payload logging
Published Jul 3, 2024 · Updated Aug 2, 2024
Information disclosure in Mattermost 9.5.0 through 9.5.5 and 9.8.0 allows remote authenticated users to read message contents via audit logs. RemoteClusterFrame audit logging writes unsanitized payloads in full, including message content, rather than redacting sensitive fields. Exploitation requires high privileges and access to audit logs generated for shared-channel traffic.
