- CVE-2026-92965, 20 Sep 2026
- The TikTok WordPress plugin before 1.4.2 does not check that a request is authorised before acting on a sign-in code supplied in the URL, so any visitor can make the site redeem a code of their choosing against the advertising platform, using the site's own credentials. It matches that code loosely, so URLs that merely resemble the expected one trigger it too, and the callback runs on every request to the site rather than only on the administrator's sign-in. CVE record
- CVE-2026-18346, 19 Sep 2026
- The TikTok plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.4.1. 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. CVE record
What to do if you run TikTok
If you run TikTok, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
