CRITICAL 9.6UPGRADE

CVE-2026-59151 is a critical-severity flaw (CVSS 9.6) affecting prowler. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Prowler is a cloud security platform. Prior to 5.30.3, Prowler's SAML authentication flow trusted the email domain asserted in a SAMLResponse when deciding which tenant should receive the final token, and the ACS finish logic in api/src/backend/api/v1/views.py recalculated the tenant from user.email instead of binding token issuance to the validated SAML configuration. An authenticated attacker with a controlled SAML IdP could complete a valid SA
