net/http: net/http/internal/http2: golang.org/x/net/http2: net/http: Denial of Service via excessive HTTP/2 SETTINGS frames
A flaw was found in the Go net/http package. This flaw allows a remote attacker to cause a Denial of Service DoS by triggering excessive CPU consumption on an affected client or server. By opening a large number of HTTP/2 streams and repeatedly sending small configuration SETTINGS frames that...
net/http: golang: golang: Denial of Service via crafted HTTP Range headers
A flaw was found in the Go net/http package. A remote attacker can cause a Denial of Service DoS by sending an HTTP request containing a Range header with a large number of small byte ranges. When the server processes these ranges while serving content, it consumes an excessive amount of CPU...

CVE-2026-23751-PoC Proof-of-concept implementation of the .NET HTTP Remoting technique described in Code White's NewRemotingTricks, targeting Tungsten Automation Kofax Capture. CVE-2026-23751 Title: Tungsten Automation Kofax Capture Unauthenticated File Read/Write and Command Execution via .NET...
BIT-GOLANG-2026-97032 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...
BIT-GOLANG-2026-94439 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...
BIT-GOLANG-2026-78669 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...
BIT-GOLANG-2026-78667 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...
BIT-GOLANG-2026-78663 Double flow control refund on HTTP/2 server streams in net/http
The HTTP/2 server can refund connection-level flow control twice for the same data: Once when a client resets a stream refunding data for any sent-but-unread portion of the stream, and again when a request handler reads the buffered data. A malicious client can exploit this to bypass the configur...
BIT-GOLANG-2026-78660 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...
BIT-GOLANG-2026-78659 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 ...
BIT-GOLANG-2026-56866 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...
