CVE-2022-1326
At a glance
CVE-2022-1326 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Form WordPress plugin, affecting versions <= 1.2.0. It carries a CVSS score of 6.1 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.2.1; sites on affected versions should update now. Disclosed June 2022.
Vulnerability Overview
The Form - Contact Form WordPress plugin through 1.2.0 does not sanitize and escape Custom text fields, which could allow high-privileged users such as admin to perform Cross-Site Scripting attacks even when unfiltered_html is disallowed
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Form <= 1.2.0 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Form the fix is 1.2.1: builds <= 1.2.0 are affected, anything from 1.2.1 onward is not.
Remediation
Update to version 1.2.1, or a newer patched version
How does WordSec protect against this?
The attempt arrives as an ordinary request to Form: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Form 1.2.1 closes this, and updating the plugin is the step that ends it.
