What is CVE-2023-6991?

The file_get_contents() Shortcode plugin for WordPress, developed by JSM, exhibits a vulnerability due to improper validation of shortcode parameters. This oversight allows users with roles of contributor and above to exploit the plugin, potentially leading to Server-Side Request Forgery (SSRF) attacks. Such SSRF vulnerabilities may enable attackers to send crafted requests to unintended internal services or resources, thereby compromising the security of the underlying server and its applications. It is essential for users of affected versions to update to version 2.7.1 or later to mitigate this risk.
