CVE-2024-13587

Zigaform – Price Calculator & Cost Estimation Form Builder Lite <= 7.4.7 - Authenticated (Contributor+) Stored Cross-Site Scripting

6.4 Medium

The Zigaform – Price Calculator & Cost Estimation Form Builder Lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'zgfm_fvar' shortcode in all versions up to, and including, 7.4.7 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
