CVE ID :CVE-2026-18346
Published : Sept. 19, 2026, 9:16 a.m. | 3 hours, 52 minutes ago
Description :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.
Severity: 5.3 | MEDIUM
