OpsTree REMS through 1.0.0 contains an improper attribution vulnerability that allows authenticated users to post comments as the incident creator via POST /api/v1/incidents/{incident_id}/comment. Lower-privileged attackers can comment on incidents owned by users such as a Super User to impersonate them and corrupt the incident timeline and audit trail.
