Description

The Go Night Pro | WordPress Dark Mode Plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'go-night-pro-shortcode' shortcode in all versions up to, and including, 1.1.0 due to insufficient input sanitization and output escaping on the user-supplied 'margin' attribute. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • hrs2015 Go Night Pro | WordPress Dark Mode Plugin — Up to and including 1.1.0
