GO-2026-6603 HTTP/2 server memory exhaustion due to Trailer headers in net/http

When "Trailer" headers are sent by a client, the HTTP server internally uses the header values to populate the Request.Trailer map passed to the server handler. Because Request.Trailer is a map, each entry incurs memory overhead. For HTTP/2 servers, a malicious client can exploit this by sending ...

GO-2026-6599 Reset context tracking on consecutive template expressions in html/template

When a JavaScript template literal contains consecutive expressions, the context tracking state was not properly reset upon entering a new expression. We now ensure that template-literal expression entries correctly reset context variables so all subsequent regular expression literals are...

GO-2026-6604 Root.Mkdir(All) can follow junctions out of the root on Windows in os

On Windows, when the target of Root.Mkdir or Root.MkdirAll is a junction pointing to an empty location, the operation can create a directory at the junction target even when that target is located outside the root. This only applies to operations where the last path component is a junction...

GO-2026-6610 HTTP/2 transport accepts malformed framing-related headers in net/http

Historically, we have been rather lax about malformed framing-related headers in our HTTP/2 implementation, as they cannot interfere with HTTP/2 framing. However, this makes it possible for our HTTP/2 implementation to forward responses containing such headers to an HTTP/1 client when acting as a...

GO-2026-6607 Reject malformed ECH outer extension references in crypto/tls

Multiple ECH outer extension references are not permitted under RFC 9849; previously, a client could send a well-crafted packet that could trigger memory exhaustion in the server process by specifying multiple references. We now reject these as malformed and curb the memory amplification vector a...

GO-2026-6609 Lack of limit on size of parsed Range headers in net/http

When parsing a Range header containing a large number of small ranges, FileServerFS, ServeContent, and ServeFileFS can consume an excessive amount of CPU...

GO-2026-6617 HTTP/2 server crash due to HPACK encoder race in net/http

HTTP/2 servers could end up crashing due to inadvertently modifying its HPACK encoder concurrently. This happens because the server modifies the HPACK encoder from two goroutines without synchronization: one uses the encoder to encode a HEADERS frame as part of a response sent to a client and the...

GO-2026-6601 Checksum bypass for golang.org/fips140 in cmd/go

Previously, a user operating inside of a malicious Go project that defines a bogus golang.org/fips140 and operates a malicious GOMODPROXY the user chooses to connect to can serve an arbitrary module in its place. We now unpack the trusted ziphash for the bundled golang.org/fips140 module and...
