CVE-2026-59151 Details
Description
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.
A vulnerability in Prowler's SAML authentication process prior to version 5.30.3 allows for cross-tenant account takeover. The issue arises because the application trusts the email domain in the SAML response when determining which tenant should receive the authentication token. An authenticated attacker with control over a SAML Identity Provider (IdP) could exploit this by completing a SAML flow for their own domain while asserting an email from a different domain. This would result in a token being issued for the wrong tenant, enabling access to the victim's account. The vulnerability is present in Prowler versions through 5.30.2.
Users should update to Prowler version 5.30.3 or later, where this vulnerability has been fixed.
