CVE CVE-2025-7045
CVSS 6.5 (Medium)
Publicly Published September 5, 2025
Last Updated September 6, 2025
Researcher kr0d

Description

The Cloud SAML SSO plugin for WordPress is vulnerable to Identity Provider Deletion due to a missing capability check on the delete_config action of the csso_handle_actions() function in all versions up to, and including, 1.0.19. This makes it possible for unauthenticated attackers to delete any configured IdP, breaking the SSO authentication flow and causing a denial-of-service.
