This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to overwrite the merchant's stored TikTok integration access token in wp_options, hijacking the site's TikTok Business and product catalog integration. Successful exploitation requires the attacker to supply a valid TikTok OAuth auth_code issued for the merchant's registered TikTok app, as the plugin's token exchange must receive a message='OK' response from TikTok's API before the stored access token is overwritten."}],"title":"TikTok <= 1.4.1 - Missing Authorization to Unauthenticated TikTok Integration Takeover via 'auth_code' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/31233f4e-4cd5-497f-9e8a-c65635596241?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/tiktok-for-business/tags/1.4.0/admin/Tt4b_Menu_Class.php#L417"},{"url":"https://plugins.trac.wordpress.org/browser/tiktok-for-business/tags/1.4.0/admin/tt4b_menu.php#L13"},{"url":"https://plugins.trac.wordpress.org/browser/tiktok-for-business/tags/1.4.0/admin/Tt4b_Menu_Class.php#L397"},{"url":"https://plugins.trac.wordpress.org/browser/tiktok-for-business/tags/1.4.0/mapi/Tt4b_Mapi_Class.php#L332"},{"url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3699236%40tiktok-for-business&new=3699236%40tiktok-for-business"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-862 Missing Authorization","cweId":"CWE-862","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","baseScore":5.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Hillary Mutai"}],"timeline":[{"time":"2026-09-18T19:51:26.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-18346","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-09-19T13:17:52.631463Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-09-19T13:51:19.729Z"}}]}}
