CVE-2024-13573: 
WordPress vulnerability analysis and mitigation

The Zigaform – Form Builder Lite plugin for WordPress contains a Stored Cross-Site Scripting vulnerability (CVE-2024-13573) that affects all versions up to and including 7.4.2. The vulnerability was discovered and reported by Peter Thaleikis, with public disclosure on February 17, 2025 (Wordfence, NVD).

The vulnerability exists due to insufficient input sanitization and output escaping on user-supplied attributes in the plugin's 'zgfm_rfvar' shortcode. The issue has been assigned a CVSS v3.1 base score of 5.4 (Medium) by NIST with a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, while Wordfence assessed it at 6.4 (Medium) with a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N. The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation) (NVD).

This vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages. These malicious scripts will execute whenever a user accesses the compromised page (NVD).

Users should update to a version newer than 7.4.2 once available. Until then, it is recommended to restrict access to the plugin's functionality to trusted users only (NVD).
