CVE-2024-11897: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in mightyforms Contact Form, Survey & Form Builder – MightyForms
The Contact Form, Survey & Form Builder – MightyForms plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'mightyforms' shortcode in all versions up to, and including, 1.3.9 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.
AI Analysis
Technical Summary
CVE-2024-11897 is a stored cross-site scripting vulnerability in the MightyForms WordPress plugin, affecting all versions up to 1.3.9. The vulnerability is due to improper neutralization of input during web page generation (CWE-79), specifically insufficient input sanitization and output escaping on user-supplied attributes within the 'mightyforms' shortcode. This allows authenticated users with contributor-level access or higher to inject arbitrary web scripts that execute when the injected page is accessed by others.
Potential Impact
Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages using the 'mightyforms' shortcode. These scripts execute in the context of users viewing the page, potentially leading to session hijacking, privilege escalation, or other client-side attacks. The impact is limited to confidentiality and integrity with no direct availability impact. The vulnerability requires authenticated access with contributor-level permissions or above.
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 removing the MightyForms plugin if possible. Monitor for updates from the vendor and apply patches promptly once released.
