CVE-2022-0278Network attack vector

Stored script execution via unescaped contact submissions

Published Jan 20, 2022 · Updated Aug 2, 2024

Stored XSS in Microweber before 1.2.11 allows attackers to execute script in an administrator's browser via a crafted contact-form submission. The administrative notification template prints scalar and array submission values directly into HTML; the patch applies htmlentities() before rendering each value. An administrator must view the stored submission, after which the script runs within that viewer's browser security context.
