Summary (supported by provided sources): The CVE-2026-15631 issue affects @fastify/http-proxy versions 9.4.0 to 11.5.0, where the WebSocket routing logic in WebSocketProxy.findUpstream validates the destination path against the rewrite prefix but relies on the WHATWG URL constructor, which collap...

CVE-2026-16158

Impact: @fastify/reply-from versions from 8.3.1 up to but not including 12.6.4 build the internal URL cache key by concatenating the destination and source path without a delimiter. Different destination and source pairs can therefore produce the same key while resolving to different upstream URL...

CVE-2026-16158

CVE-2026-16158 affects @fastify/reply-from. The vulnerability stems from how the internal URL cache key is built by concatenating the destination and source paths without a delimiter in versions 8.3.1 up to (but not including) 12.6.4. This can cause key collisions where different upstreams resolv...

CVE-2026-14198

@fastify/middie versions 9.1.0 through 9.3.2 decode the encoded slash %2F inside path parameter values before matching middleware paths, while Fastify's underlying router preserves the encoding during route lookup. The two layers disagree on the canonical request path, so the middleware fails to...
