{"cve":"CVE-2025-7040","nvd":{"published":"2025-09-06T04:16:02.867","modified":"2026-06-17T10:04:08.933","status":"Deferred","description":"The Cloud SAML SSO plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'set_organization_settings' action of the csso_handle_actions() function in all versions up to, and including, 1.0.19. The handler reads client-supplied POST parameters for organization settings and passes them directly to update_option() without any check of the user’s capabilities or a CSRF nonce. This makes it possible for unauthenticated attackers to change critical configuration (including toggling signing and encryption), potentially breaking the SSO flow and causing a denial-of-service.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L","score":8.2},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/cloud-sso-single-sign-on/tags/1.0.19/assets/CSSO_Init.php","https://plugins.trac.wordpress.org/browser/cloud-sso-single-sign-on/tags/1.0.19/assets/base/CSSO_ActionHandler.php","https://plugins.trac.wordpress.org/browser/cloud-sso-single-sign-on/tags/1.0.19/assets/base/CSSO_services.php","https://plugins.trac.wordpress.org/browser/cloud-sso-single-sign-on/tags/1.0.19/saml-sso-plugin.php","https://plugins.trac.wordpress.org/browser/cloud-sso-single-sign-on/trunk/assets/base/CSSO_ActionHandler.php?rev=3354459#L202"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:08:41.295252406+00:00"},"epss":{"cve":"CVE-2025-7040","score":0.00291,"percentile":0.21661,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
