Summary

The TikTok plugin for WordPress is vulnerable to authorization bypass in all versions up to and including 1.4.1 due to the plugin not properly verifying that a user is authorized to perform an action. This allows 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.

Risk Assessment

The risk includes TikTok account takeover, product catalog manipulation, and potential customer data theft.

Recommendation

It is recommended to update the plugin to the latest version and monitor logs for unauthorized token changes.

Original NVD description (English source)

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.
