{“lastseen”:””,”description”:”The OAuth Single Sign On \u2013 SSO (OAuth Client) plugin for WordPress is vulnerable to Improper Verification of Cryptographic Signature in versions up to, and including, 6.26.12. This is due to the plugin performing unsafe JWT token processing without verification or validation in the `get_resource_owner_from_id_token` function. This makes it possible for unauthenticated attackers to bypass authentication and gain access to any existing user account – including administrators in certain configurations – or to create arbitrary subscriber-level accounts.”,”published”:”2025-10-04T02:24:37.169Z”,”modified”:”2025-10-04T02:24:37.169Z”,”type”:”cve”,”title”:”OAuth Single Sign On \u2013 SSO (OAuth Client) \\u003c= 6.26.12 – Authentication Bypass via get_resource_owner_from_id_token()”,”source”:”Wordfence”,”references”:”https:\/\/www.wordfence.com\/threat-intel\/vulnerabilities\/id\/d2448afc-70d1-4dd5-b73b-62d182ee9a8a?source=cve\\nhttps:\/\/plugins.trac.wordpress.org\/browser\/miniorange-login-with-eve-online-google-facebook\/tags\/6.26.12\/class-mooauth-widget.php#L577\\nhttps:\/\/plugins.trac.wordpress.org\/changeset\/3360768\/miniorange-login-with-eve-online-google-facebook”,”id”:”CVE-2025-9485″,”bulletinFamily”:””,”cwe”:[“CWE-347″],”cvelist”:null,”sourceData”:”cyberlord92 OAuth Single Sign On \u2013 SSO (OAuth Client) *”,”sourceHref”:””,”cvss”:{“score”:9.8,”severity”:”CRITICAL”,”vector”:”CVSS:3.1\/AV:N\/AC:L\/PR:N\/UI:N\/S:U\/C:H\/I:H\/A:H”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”OAuth Single Sign On \u2013 SSO (OAuth Client)”,”version”:”*”,”vendor”:”cyberlord92″,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
