At a glance

CVE-2025-7045 is a medium-severity Missing Authentication for Critical Function vulnerability in the Cloud SAML SSO WordPress plugin, affecting versions <= 1.0.19. It carries a CVSS score of 6.5 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.0.20; sites on affected versions should update now. Disclosed September 2025, reported by kr0d.

Vulnerability Overview

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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-306: Missing Authentication for Critical Function

The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.

Remediation

Update to version 1.0.20, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Cloud SAML SSO 1.0.20 closes this, and updating the plugin is the step that ends it.
