Technical details

The Kali Forms plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) due to insufficient input sanitization and output escaping on the 'digitalSignature' field value. An unauthenticated attacker can exploit this by submitting a form containing malicious JavaScript. Because the required form-submission nonce is publicly available on pages where the form is published, there are no significant preconditions for the attack. The injected script is stored and executes in the context of any user (including administrators) who views the submission or the page where the data is displayed. This vulnerability affects all versions up to and including 2.4.18.
