CVE-2026-96227 · Severity: high · CVSS 8.8 · Published 2026-10-11

Piotnet Forms is a WordPress plugin for creating custom forms. The plugin fails to authenticate file uploads in form submissions and allows browser-executable files to be stored, letting unauthenticated attackers upload a malicious file that executes arbitrary JavaScript when opened. An attacker can exploit this to steal user credentials, deface the site, or compromise visitors.

## Technical details

The plugin lacks authentication and validation on form-submission file-upload endpoints, permitting unauthenticated attackers to upload browser-renderable file types (e.g., HTML, SVG). When a stored file is accessed, arbitrary JavaScript executes in the site's origin (stored XSS), giving the attacker access to session tokens, user data, or site administration. No patch is currently available.
