description

Tracecat Docker Compose deployments with SAML enabled are affected from version 0.37.0 through versions before 1.0.0-beta.49. An unauthenticated attacker able to reach the SAML assertion consumer endpoint may obtain a session for an existing user by submitting a forged unsigned SAML response. Helm and Fargate deployments are not affected.

mitigation

Upgrade Tracecat to version 1.0.0-beta.49 or later. Until upgraded, restrict access to the SAML assertion consumer endpoint and ensure SAML assertion and response signature verification remains required.

fixed in 1.0.0-beta.49
