CVE-2026-107714: Exposure of Sensitive Information to an Unauthorized Actor

The Mechanize library is used for automating interaction with websites. Prior to 2.14.1, Mechanize::HTTP::Agentresponseredirect treats redirects as same-origin when the host matches without consistently comparing scheme and port. A same-host HTTPS-to-HTTP redirect can send Authorization and Cooki...

CVE-2026-78660: Inconsistent Interpretation of HTTP Requests

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...

CVE-2026-78659: Asymmetric Resource Consumption (Amplification)

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 ...

CVE-2026-56866: Inconsistent Interpretation of HTTP Requests

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-2026-78663: Multiple Operations on Resource in Single-Operation Context

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-2026-94439: Inconsistent Interpretation of HTTP Requests

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...

PT-2026-108702

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...
