The vulnerability exists within the verify_twitter_callback function because after exchanging the visitor's oauth_verifier for their access token, the handler never calls setOauthToken() to reassign the returned credentials to the TwitterOAuth client, causing the subsequent account/verify_credentials API call to remain signed with the site operator's stored Access Token and Access Token Secret rather than the authenticating visitor's token. This causes the X API to return the profile of the X application owner instead of the signing-in visitor, and the plugin then resolves and authenticates a WordPress account solely by matching that owner's email address via wp_set_auth_cookie(), allowing unauthenticated attackers to gain authenticated access as the WordPress user whose email corresponds to the X app owner, who is typically the site administrator.","severity":"critical","score":9.8,"published":"2026-10-28T01:30:48.320Z","modified":"2026-10-28T01:30:48.320Z","withdrawn":false,"knownExploited":false,"affected":[],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/1ad42de2-9ed1-4cf6-a031-22789be4cbe2?source=cve","https://plugins.trac.wordpress.org/changeset/3759312/jupiterx-core/trunk/includes/extensions/raven/includes/modules/forms/classes/social-login-handler/twitter.php"],"sources":[{"name":"CVE","id":"CVE-2026-106013","modified":"2026-10-28T01:30:48.320Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-106013"}],"assessments":[{"source":"Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8}],"sourceAffected":[],"kev":{"status":"not-listed","checkedAt":"2026-10-28T19:15:31.108Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[]}
