AI Powered Q&A
Can you explain this vulnerability to me?
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.
How can this vulnerability impact me? :
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.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
