  "title": "TLS certificate validation bypass in @fastify/reply-from",
  "summary": "@fastify/reply-from releases earlier than 12.7.0 may accept an untrusted certificate when forwarding requests to an HTTPS upstream through built-in transports. An attacker positioned to intercept that upstream connection could inspect forwarded sensitive data or provide responses posing as the upstream service.",
  "mitigation": "Upgrade @fastify/reply-from to 12.7.0 or later. Until upgrading, explicitly enable upstream certificate validation or use a preconfigured Undici client or global agent that enforces it.",
