CVE-2026-95864: Themify Builder plugin stored cross-site scripting in font CSS parameter

CVE-2026-95864 · Severity: high · CVSS 7.2 · Published 2026-09-25

The Themify Builder plugin for WordPress allows website designers to customize site appearance through page templates and styling. An unauthenticated attacker can inject malicious JavaScript into the site's CSS settings via the 'css[fonts]' parameter, which executes when any visitor accesses an affected page. The vulnerability exists because the plugin fails to properly sanitize user input and the security token needed to exploit it is exposed in publicly visible page code.

Vendors: Themify.

Technical details

The Themify Builder plugin contains a stored XSS vulnerability in its CSS stylesheet handler due to insufficient input sanitization and output escaping of the 'css[fonts]' parameter. The vulnerable endpoint requires only a CSRF nonce token that is embedded in plain text in front-end page markup, making it accessible to unauthenticated attackers. Successful exploitation allows arbitrary JavaScript injection that persists in the database and executes in users' browsers when viewing affected pages.
