# CVE-2022-1393: WP Subtitle \< 3.4.1 - Contributor+ Stored Cross-Site Scripting

- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 3.4.1
- Published: 2022-05-16 · Updated: 2024-08-03

## Affected

- Unknown WP Subtitle: from 3.4.1, fixed in 3.4.1

## Description

The WP Subtitle WordPress plugin before 3.4.1 adds a subtitle field and provides a shortcode to display it via [wp_subtitle]. The subtitle is stored as a custom post meta with the key: "wps_subtitle", which is sanitized upon post save/update, however is not sanitized when updating it directly from the post meta update button (via AJAX) - and this makes the XSS exploitable by authenticated users with a role as low as contributor.

## What to do
