{"id":"CVE-2025-7040","url":"https://www.cyber-defence.io/tools/cve/CVE-2025-7040","generatedAt":"2026-10-28T04:16:50.339Z","title":"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.","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.","published":"2025-09-06T04:16:03.000Z","lastModified":"2026-06-17T10:04:09.000Z","status":"Deferred","sourceIdentifier":"security@wordfence.com","cvss":{"version":"3.1","score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:L"},"cwe":["CWE-862"],"affected":[],"epss":{"score":0.00291,"percentile":0.21493,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.29%).
