CVE-2025-0469 in Forminator Forms Plugin
Summary
by MITRE • 02/27/2025
The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the slider template data in all versions up to, and including, 1.39.2 due to insufficient input sanitization and output escaping. 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.

The vulnerability identified as CVE-2025-0469 affects the Forminator plugin for WordPress, specifically targeting versions up to and including 1.39.2. This represents a critical security flaw that undermines the integrity of web applications built on WordPress platforms. The issue stems from inadequate input sanitization and output escaping mechanisms within the plugin's slider template functionality, creating a persistent vector for malicious code injection.
The technical flaw manifests through stored cross-site scripting vulnerabilities that occur when slider template data is processed within the plugin's framework. Attackers with Contributor-level access or higher can exploit this weakness by injecting malicious scripts into form templates that are then stored within the WordPress database. These stored scripts execute whenever any user accesses pages containing the compromised slider templates, creating a persistent threat that can affect multiple users over time. The vulnerability operates under CWE-79 which specifically addresses Cross-Site Scripting flaws, and aligns with ATT&CK technique T1566.001 for Initial Access through Spearphishing Attachments.
The operational impact of this vulnerability extends beyond simple script execution, as it enables attackers to perform various malicious activities including credential theft, session hijacking, and data exfiltration. The stored nature of the XSS vulnerability means that compromised pages remain dangerous even after the initial attack, as the injected scripts persist in the database and execute for every visitor. This creates a significant risk for websites using the Forminator plugin, particularly those with multiple contributors or users with elevated privileges.
Mitigation strategies should prioritize immediate plugin updates to versions that address this vulnerability, as developers typically release patches to resolve such security issues. Organizations should also implement strict input validation measures, enforce proper output escaping for all user-generated content, and consider implementing content security policies to limit the execution of unauthorized scripts. Additionally, access controls should be reviewed to ensure that only necessary users have Contributor-level permissions or higher, reducing the attack surface available to potential adversaries. The vulnerability demonstrates the importance of regular security audits and keeping all WordPress plugins updated to protect against known exploits.
