Undici

A vulnerability in undici's ProxyAgent, when configured with a SOCKS5 proxy, causes the `requestTls` option to be silently dropped. This bypasses user-configured TLS certificate validation settings (e.g., custom CAs), allowing HTTPS connections through the SOCKS5 tunnel to fall back to the Node.js default trust store. This flaw enables Man-in-the-Middle (MITM) attacks, where any publicly-trusted certificate for the target hostname would be accepted, compromising the intended certificate pinning and allowing attackers to read or tamper with HTTPS traffic.
