CVE-2025-5341: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in wpmudev Forminator Forms – Contact Form, Payment Form & Custom Form Builder
The Forminator Forms – Contact Form, Payment Form & Custom Form Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘id' and 'data-size’ parameters in all versions up to, and including, 1.44.1 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.
AI Analysis
Technical Summary
The Forminator Forms – Contact Form, Payment Form & Custom Form Builder WordPress plugin suffers from a stored cross-site scripting vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the 'id' and 'data-size' parameters are not properly sanitized or escaped, allowing authenticated users with Contributor or higher privileges to inject arbitrary scripts. These scripts execute in the context of users who access the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to 1.44.1 and has a CVSS 3.1 base score of 6.4 (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N).
Potential Impact
An attacker with Contributor-level or higher access can inject persistent malicious scripts into pages generated by the plugin. These scripts execute in the browsers of users who view the compromised pages, potentially leading to limited confidentiality and integrity impacts such as theft of user data or session tokens. There is no impact on availability. The vulnerability requires authentication and low attack complexity but affects multiple users due to stored script execution.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or limiting use of the affected plugin. Monitor vendor channels for updates and apply any official patches promptly once released.
