SCA: security update for @fastify/http-proxy, @fastify/reply-from (GHSA-gwhp-pf74-vj37)
critical Tenable Self-Hosted Container Security Plugin ID 440471
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- @fastify/reply-from v12.6.1 and earlier and @fastify/http-proxy v11.4.3 and earlier 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 from upstream requests by listing them in the
Connection header value. Any header added by the proxy for routing, access control, or security purposes
can be selectively removed by a client. @fastify/http-proxy is also affected as it delegates to
@fastify/reply-from. Upgrade to @fastify/reply-from v12.6.2 or @fastify/http-proxy v11.4.4 or later.
(CVE-2026-33805)

Update the @fastify/http-proxy library and its related packages to version 11.4.4 or later.See Also
