This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the GitHub Gist Shortcode Plugin for WordPress. It occurs via the 'id' parameter of the 'gist' shortcode in all versions up to and including 0.2. The problem is caused by insufficient input sanitization and output escaping, allowing authenticated users with Contributor-level access or higher to inject malicious web scripts.

How can this vulnerability impact me? :

This vulnerability can allow attackers with Contributor-level access or higher to inject malicious scripts into pages, which will execute in the browsers of users who view those pages. This can lead to theft of user credentials, session hijacking, defacement, or other malicious actions performed on behalf of the victim user without their consent.
