- Severity: CVSS 6.1 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no

## Affected

- codename065 Download Manager: through 3.3.46

## Description

The Download Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'redirect_to' parameter in all versions up to, and including, 3.3.46. This is due to insufficient input sanitization and output escaping on the 'redirect_to' GET parameter in the login form shortcode. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.
