What the vulnerability does
01Description
The B Carousel Block – Responsive Image and Content Carousel plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including, 1.1.5. This is due to the plugin not validating user-supplied URLs before passing them to the wp_remote_request() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
Explanation of Vulnerability in Simple Terms

The Carousel Block plugin for WordPress contains a server-side request forgery (SSRF) vulnerability that allows authenticated users to make the site send HTTP requests to internal or external systems on the attacker's behalf. An attacker with low-level access can exploit this to access internal services, retrieve sensitive data, or interact with systems behind the site's firewall. The vulnerability affects versions 1.1.5 and earlier.
