Descripción

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 SAML flow for an attacker-controlled domain while asserting an email address from another configured domain, causing a SAMLToken and tenant-scoped JWT to be issued for the wrong tenant and enabling cross-tenant account takeover. This issue is fixed in version 5.30.3.
