Can you explain this vulnerability to me?
This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Nexter Extension – Site Enhancements Toolkit plugin for WordPress. It occurs via the plugin's 'nxt-year' shortcode in versions up to 4.4.1 due to insufficient input sanitization and output escaping. Authenticated users with Contributor-level access or higher can inject malicious scripts into pages, which then execute whenever any user accesses those pages.
How can this vulnerability impact me? :
The vulnerability allows attackers with Contributor-level access or higher to inject arbitrary web scripts into pages. This can lead to unauthorized actions such as stealing user session data, defacing websites, or performing actions on behalf of other users without their consent, potentially compromising the security and integrity of the affected website.
