AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Extra Post Images plugin for WordPress. It occurs via the 'id' parameter of the extra-images shortcode in versions up to and including 1.0. Due to insufficient input sanitization and output escaping, authenticated users with Contributor-level access or higher can inject malicious scripts into pages. These scripts execute whenever any user accesses the injected page.
How can this vulnerability impact me? :
The vulnerability allows attackers with Contributor-level access or above to inject arbitrary scripts into WordPress pages. This can lead to unauthorized actions such as stealing user session data, defacing the website, or performing actions on behalf of other users without their consent. It compromises the integrity and security of the website and its users.
