CVE-2026-11581 · Severity: info · CVSS 5.9 · Published 2026-06-30

A security vulnerability exists in the Kali Forms WordPress plugin, which is used to create contact forms and manage user submissions. Users with low-level 'Contributor' access can inject malicious scripts into form field captions. When a site administrator views the form entries, these scripts execute in their browser, potentially allowing the attacker to perform administrative actions or take over the site.

## Technical details

The Kali Forms plugin fails to sanitize form field captions before displaying them as column headers on the administrator's form-entries screen. While Contributors are normally restricted from publishing forms, a missing capability check in the 'kaliforms_duplicate_post' AJAX action allows them to bypass this restriction and publish a malicious draft. An attacker can use the WordPress REST API to inject a payload into the 'kaliforms_field_components' meta field and then use the duplication flaw to ensure the form is rendered for an administrator. This results in Stored XSS (CWE-79) that can be used for privilege escalation, such as creating a new administrator account via the wp.apiFetch API.
