AZL-107928 CVE-2026-56866 affecting package tensorflow 2.16.1-11

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...

AZL-107853 CVE-2026-56866 affecting package python-tensorboard 2.16.2-6

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...

CVE-2026-78667

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-2026-97032 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...

EUVD-2026-95429

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...

CVE-2026-97032

HTTP/2 servers are vulnerable to a crash caused by a race condition in the HPACK encoder . The issue occurs because the server modifies the encoder from two goroutines without proper synchronization: one goroutine encodes a HEADERS frame for a client response, while another modifies the encoder's...

CVE-2026-94439

An HTTP server handler is vulnerable to request smuggling because it improperly handles HTTP/1 CONNECT requests. When the handler sends a 2xx response without hijacking the connection, it fails to stop treating the connection as HTTP, even though it has been converted into a tunnel. This discrepa...

CVE-2026-78663

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...

CVE-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...

CVE-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...

CVE-2026-78660

The HTTP/2 implementation is vulnerable to response smuggling because it allows malformed framing-related headers that do not interfere with HTTP/2 framing. When acting as a reverse proxy , the implementation may forward these headers to an HTTP/1 client . If the client also lacks strict behavior...

CVE-2026-94439

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...

CVE-2026-78660

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...
