n8n before 2.38.0 and 3.x before 3.0.1 contains a missing authentication vulnerability in the Asana Trigger that accepts a new webhook verification secret from any request carrying an X-Hook-Secret header. Unauthenticated attackers who know the webhook URL can replace the secret, send forged Asana events that pass signature verification, and trigger workflows with attacker-controlled data while genuine deliveries are rejected.
