Go Night Pro WordPress Dark Mode Plugin Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Go Night Pro WordPress Dark Mode Plugin, affecting all versions through 1.1.0. The issue arises from inadequate input sanitization and output escaping of the user-supplied 'margin' attribute in the 'go-night-pro-shortcode' shortcode. This vulnerability allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages, which are executed when users access the affected page.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Reproduction

To reproduce this vulnerability, an authenticated user with contributor-level access or higher can use the 'go-night-pro-shortcode' shortcode and include a malicious script in the 'margin' attribute. Once the shortcode is saved, the injected script will execute when the page is viewed.

Remediation

No known patch is available. It is recommended to uninstall the affected plugin and find a replacement.
