CVE-2026-85124
@fastify/http-proxy versions before 11.6.2 are vulnerable to a path traversal (CWE-22) caused by insufficient validation of backslash-based dot-segments in proxied HTTP request paths. The plain HTTP handler skips the destination validation performed on the WebSocket path, and the underlying reply...
CVE-2026-85124 @fastify/http-proxy vulnerable to prefix escape via backslash dot-segments
@fastify/http-proxy versions before 11.6.2 do not validate proxied HTTP request paths for backslash based dot-segments before forwarding them to the configured upstream. The plain HTTP request handler skips the destination validation that the WebSocket path performs, and the underlying reply-from...

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-2026-33805
A flaw was found in @fastify/reply-from and @fastify/http-proxy. A remote attacker can exploit this vulnerability by manipulating the Connection header in client requests. This allows the attacker to remove specific headers that the proxy has added for security, routing, or access control purpose...
Fastify's connection header abuse enables stripping of proxy-added headers
Summary @fastify/reply-from and @fastify/http-proxy process the client's Connection header after the proxy has added its own headers via rewriteRequestHeaders. This allows attackers to retroactively strip proxy-added headers like access control or identification headers from upstream requests by...
