CVE-2026-94447 Checksum database bypass for golang.org/toolchain in cmd/go

Previously, a user operating inside of a malicious Go project that defines a bogus golang.org/toolchain go.sum entry and operates a malicious GOMODPROXY the user chooses to use can bypass the intended checksum. We now ensure that golang.org/toolchain always goes to the network for the canonical...

CVE-2026-94448

The html/template package in Go is vulnerable because the context tracking state was not properly reset when a JavaScript template literal contained consecutive expressions. This flaw prevents subsequent regular expression literals from being accurately recognized and escaped. The fix ensures tha...

CVE-2026-97030 Recognize yield as regexp preceder keyword in html/template

A trusted template author may have previously written a valid template wherein the use of the 'yield' keyword would not be correctly escaped. We now ensure that valid keyword uses are escaped and non-keyword uses are not escaped...

CVE-2026-97030

The html/template package in Go is affected by an issue where the 'yield' keyword, when used as a regexp preceder keyword, might not be correctly escaped in templates authored by a trusted source. The vulnerability arises from inconsistent escaping logic for valid versus non-keyword uses. Remedia...

CVE-2026-94448 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...

The flaw carries a CVSS 4.0 score of 9.3 and can be exploited remotely without authentication or user interaction. Becaus...

GO-2026-6602 Checksum database bypass for golang.org/toolchain in cmd/go

Previously, a user operating inside of a malicious Go project that defines a bogus golang.org/toolchain go.sum entry and operates a malicious GOMODPROXY the user chooses to use can bypass the intended checksum. We now ensure that golang.org/toolchain always goes to the network for the canonical...

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...

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-2026-6611 Excessive CPU consumption from repeated initial window changes in net/http

A malicious HTTP/2 peer can cause excessive CPU consumption in the client or server by opening a large number of streams and then sending many small SETTINGS frames containing SETTINGSINITIALWINDOWSIZE values...

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-2026-6609 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-2026-6605 HTTP/1 client connection desynchronization after CONNECT rejection in net/http

When http.Transport sends an HTTP/1 CONNECT request with a non-empty Request.Body, it writes the body directly to the connection without framing after the request headers. If the server rejects the CONNECT request with a non-2xx keep-alive response, Transport returns the connection to the idle...

GO-2026-6608 Memory limit bypass when parsing MIME headers in net/textproto, mime/multipart

Parsing a multipart form can bypass memory limits and read an arbitrarily long line into memory when the remaining limit at the start of a part is less than 400 bytes...

GO-2026-6613 HTTP/1 server connection desynchronization after 2xx CONNECT response in net/http

When an HTTP server handler sends a 2xx response to an HTTP/1 CONNECT request and returns without hijacking the connection, the server improperly continues to read and serve requests from the connection. Since a 2xx response to an HTTP/1 CONNECT converts the connection into a tunnel, the server...

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-2026-6604 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...
