Background
fibjs is an npm package that provides a JavaScript runtime environment for developing server-side applications. It offers a range of features and functionalities to facilitate web development. However, certain versions of fibjs are vulnerable to an insecure download issue, where an executable is downloaded over an unencrypted HTTP connection. This vulnerability can be exploited by attackers with privileged network positions to intercept the response and replace the executable with a malicious one, potentially leading to code execution on the system running fibjs.
