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.","state":0,"publishedAt":"2026-10-28T01:30:48.32+00:00","modifiedAt":"2026-10-29T01:52:00.079+00:00","affected":[{"ecosystem":"Vendor product","name":"Jupiter X Core","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"artbees\",\n                    \"product\": \"Jupiter X Core\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"4.61.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-106013","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-106013","identifiers":["CVE-2026-106013"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
