# CVE-2021-24705: NEX-Forms \< 8.4.3 - Stored Cross-Site Scripting via CSRF

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 8.4.3
- Published: 2021-12-13 · Updated: 2024-08-03

## Affected

- Unknown NEX-Forms: fixed in 8.4.3

## Description

The NEX-Forms WordPress plugin before 8.4.3 does not have CSRF checks in place when editing a form, and does not escape some of its settings as well as form fields before outputting them in attributes. This could allow attackers to make a logged in admin edit arbitrary forms with Cross-Site Scripting payloads in them

## What to do
