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."}], "title": "Jupiter X Core <= 4.61.0 - Unauthenticated Authentication Bypass via Twitter/X Social Login oauth_verifier Parameter", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/1ad42de2-9ed1-4cf6-a031-22789be4cbe2?source=cve"}, {"url": "https://plugins.trac.wordpress.org/changeset/3759312/jupiterx-core/trunk/includes/extensions/raven/includes/modules/forms/classes/social-login-handler/twitter.php"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-287 Improper Authentication", "cweId": "CWE-287", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H", "baseScore": 9.8, "baseSeverity": "CRITICAL"}}], "credits": [{"lang": "en", "type": "finder", "value": "daroo"}], "timeline": [{"time": "2026-10-06T12:31:02.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-10-27T11:37:04.000Z", "lang": "en", "value": "Disclosed"}]}}}
