AI-suggested
Users should monitor the vendor's advisory channels for updates. Until a fix is available, consider disabling or restricting access to the vulnerable functionality or plugin. Implementing web application firewall (WAF) rules to detect and block malicious payloads targeting the 'css[fonts]' parameter may provide temporary mitigation.
Description
The Themify Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'css[fonts]' Parameter in all versions up to, and including, 7.8.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The nonce required to reach the vulnerable endpoint is embedded in plain sight within the front-end page markup for all visitors, reducing the access control to a CSRF token rather than an authentication barrier and making the endpoint fully exploitable by unauthenticated attackers.
