{"id":"CVE-2026-106013","state":"PUBLISHED","title":"Jupiter X Core <= 4.61.0 - Unauthenticated Authentication Bypass via Twitter/X Social Login oauth_verifier Parameter","description":"The Jupiter X Core plugin for WordPress is vulnerable to Authentication Bypass via the Twitter/X Social Login handler in all versions up to and including 4.61.0. 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.","publishedAt":"2026-10-28T01:30:48.320Z","updatedAt":"2026-10-29T01:52:00.079Z","severity":{"score":9.8,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","source":"Wordfence"},"assigner":"Wordfence","products":["artbees Jupiter X Core"],"affected":[{"vendor":"artbees","product":"Jupiter X Core","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.61.0","versionType":"semver"}]}],"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"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:10:23.711Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/106xxx/CVE-2026-106013.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-106013","state":"PUBLISHED","datePublished":"2026-10-28T01:30:48.320Z","dateUpdated":"2026-10-29T01:52:00.079Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-10-06T12:15:24.328Z"},"containers":{"cna":{"title":"Jupiter X Core <= 4.61.0 - Unauthenticated Authentication Bypass via Twitter/X Social Login oauth_verifier Parameter","descriptions":[{"lang":"en","value":"The Jupiter X Core plugin for WordPress is vulnerable to Authentication Bypass via the Twitter/X Social Login handler in all versions up to and including 4.61.0.
