Assigner: Wordfence

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.

Executive Summary

The Go Night Pro WordPress Dark Mode Plugin is vulnerable to Stored Cross-Site Scripting (XSS) through its 'go-night-pro-shortcode' shortcode. This vulnerability exists in all versions up to and including 1.1.0 because the plugin does not properly sanitize or escape user input for the 'margin' attribute. As a result, authenticated users with contributor-level access or higher can inject malicious scripts that will execute whenever any user views the affected page.

Impact Analysis

This vulnerability allows attackers with contributor-level access or above to inject arbitrary scripts into pages. These scripts can execute in the context of other users visiting the page, potentially leading to theft of user credentials, session hijacking, defacement, or distribution of malware. The impact includes loss of data integrity and confidentiality, and it can compromise the security of the affected WordPress site.
