AI Powered Q&A
Can you explain this vulnerability to me?
The Mixlr Shortcode plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in all versions up to 1.0.1. This occurs because the plugin does not properly sanitize or escape the 'url' attribute in the 'mixlr' shortcode. As a result, authenticated users with contributor-level access or higher can inject malicious scripts into pages, which will execute whenever any user views those pages.
How can this vulnerability impact me? :
This vulnerability allows attackers with contributor-level access or higher to inject arbitrary JavaScript into pages. This can lead to unauthorized actions such as stealing user session cookies, defacing the website, redirecting users to malicious sites, or performing actions on behalf of other users without their consent.
What immediate steps should I take to mitigate this vulnerability?
The Mixlr Shortcode plugin has been temporarily closed and is no longer available for download pending a full review. Immediate mitigation steps include disabling or uninstalling the Mixlr Shortcode plugin from your WordPress installation to prevent exploitation of the stored cross-site scripting vulnerability. [2]
