HighCVSS 7.2Exploitation Probability (EPSS)
Low risk16th percentile - higher than 16% of all known CVEs
Summary
The Kali Forms plugin for WordPress (versions up to 2.4.18) is vulnerable to stored XSS via the 'digitalSignature' field. Insufficient input sanitization and output escaping allow unauthenticated attackers to inject arbitrary scripts that execute when users access the affected page.
Risk Assessment
Attackers can hijack admin sessions, steal form data, or redirect users to malicious sites, leading to data confidentiality and integrity breaches and loss of trust.
Recommendation
Immediately update the Kali Forms plugin to the latest version (above 2.4.18) and remove any suspicious content from 'digitalSignature' fields in existing forms.
Other vulnerabilities in Kali Forms
See all- CVE-2026-59542High
The Kali Forms plugin version 2.4.18 and earlier allows a user with the Subscriber role to delete arbitrary files on the server. The vulnerability does not require special privileges beyond a standard subscriber account.
- CVE-2026-81276Medium
Kali Forms version 2.4.23 and earlier has an Unauthenticated Broken Access Control vulnerability. This means an unauthenticated attacker can access functions that should be protected.
- CVE-2026-16144High
The Kali Forms plugin for WordPress is vulnerable to remote code execution via the `_save_data()` function. Insufficient validation of the `thisPermalink` field allows unauthenticated attackers to pass a controlled string to `call_user_func()`, enabling code execution on the server.
- CVE-2026-65446High
A Cross Site Scripting (XSS) vulnerability in the Kali Forms plugin for WordPress versions up to 2.4.18. An unauthenticated attacker can inject a malicious script.
- CVE-2026-11580Medium
The Kali Forms WordPress plugin before version 2.4.17 lacks a per-object capability check in its post-duplication AJAX action, allowing users with Contributor-level access or above to duplicate any post (regardless of owner, post type, or status) into a published post they own and read its private post metadata, including secrets stored by the plugin.
- CVE-2026-11579Medium
The Kali Forms WordPress plugin before version 2.4.17 does not verify that a file upload is associated with an existing form configured with a file-upload field, allowing unauthenticated users to upload files to the WordPress Media Library. Uploads are limited to default-allowed MIME types, so code execution is not possible.
- CVE-2026-9107Medium
The Kali Forms plugin for WordPress up to version 2.4.13 is vulnerable to Stored XSS via the 'meta[kaliforms_field_components]' parameter. Authenticated attackers with contributor-level access or higher can inject arbitrary scripts that execute when a user visits the compromised page.
- CVE-2026-11581Medium
The Kali Forms WordPress plugin before 2.4.13 does not sanitize a form field's caption before outputting it as a column header on the admin form-entries screen. Users with Contributor-level access or above can inject JavaScript that executes in an administrator's session. A missing capability check in the post-duplication action allows the Contributor to publish the malicious form so an administrator renders it.
Original NVD description (English source)
The Kali Forms — Contact Form & Drag-and-Drop Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'digitalSignature' Field Value in all versions up to, and including, 2.4.18 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The required form-submission nonce is publicly available on any page containing the form shortcode, making this exploitable by fully unauthenticated attackers without any precondition beyond the form being published.
