- Severity: CVSS 5.5 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:N

## Affected

- uscnanbu Welcart e-Commerce: through 2.11.22

## Description

The Welcart e-Commerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'order_mail' setting in versions up to, and including, 2.11.22. This is due to insufficient sanitization on the order_mail field and a lack of escaping on output. This makes it possible for authenticated attackers, with Editor-level permissions and above, to inject arbitrary web scripts via the General Setting page that will execute when an administrator accesses the E-mail Setting page.
