CVE-2026-95864
HighCVSS 7.2Exploitation Probability (EPSS)
Low risk17th percentile - higher than 17% of all known CVEs
Summary
The Themify Builder plugin for WordPress (up to and including 7.8.1) is vulnerable to Stored Cross-Site Scripting (XSS) via the 'css[fonts]' parameter due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts into pages that execute when a user visits the 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 access control to a CSRF token rather than an authentication barrier and making the endpoint fully exploitable by unauthenticated attackers.
Risk Assessment
Attackers can execute arbitrary JavaScript in the user's browser, leading to session theft, redirects, or other drive-by attacks.
Recommendation
Update the Themify Builder plugin to a version newer than 7.8.1. If update is not possible, implement additional input sanitization and output escaping, and consider restricting access to the vulnerable endpoint.
Other vulnerabilities in Themify Builder
See all- CVE-2026-75027Medium
The Themify Builder plugin for WordPress up to version 7.8.0 is vulnerable to authorization bypass due to improper verification of user permissions. Unauthenticated attackers can modify the stored styling data (padding and margin properties) of arbitrary posts, including private and draft posts, by supplying a post ID and JSON payload.
- CVE-2026-15407Medium
The Themify Builder plugin for WordPress up to version 7.7.7 contains an authorization bypass vulnerability. Authenticated attackers with subscriber-level access or higher can overwrite or delete generated CSS stylesheets of arbitrary posts, including private and draft posts of other users, and modify plugin-scoped font options. The CSRF nonce (tf_nonce) is exposed on public front-end pages, making it easily obtainable.
- CVE-2026-57369High
The Themify Builder plugin for WordPress contains a reflected XSS (Cross-site Scripting) vulnerability due to improper input neutralization during page generation. The issue affects versions up to and including 7.7.4.
- CVE-2026-15097Medium
The Themify Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'height_slider' Slider Module Field in all versions up to and including 7.7.6 due to insufficient input sanitization and output escaping.
- CVE-2026-15096Medium
The Themify Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'b_width_map' field in the Map Module in all versions up to and including 7.7.6 due to insufficient input sanitization and output escaping.
Original NVD description (English source)
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.
