Axios versions prior to 1.15.1 and 0.31.1 contain a flaw that allows attackers to bypass NO_PROXY settings using specific loopback addresses. If your Node.js backend uses Axios to fetch user-provided URLs or relies on proxy configurations for security isolation, you should upgrade to the fixed versions to prevent potential Server-Side Request Forgery (SSRF) attacks.
