An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection.

On Darwin, building a Go module which contains CGO can trigger arbitrary code execution when using the Apple version of ld, due to usage of the -lto_library flag in a "#cgo LDFLAGS" directive.

The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected for IPv4-mapped IPv6 addresses, returning false for addresses which would return true in their traditional IPv4 forms.

Traefik is an HTTP reverse proxy and load balancer. In affected versions sending a GET request to any Traefik endpoint with the "Content-length" request header results in an indefinite hang with the default configuration. This vulnerability can be exploited by attackers to induce a denial of service. This vulnerability has been addressed in version 2.11.2 and 3.0.0-rc5. Users are advised to upgrade. For affected versions, this vulnerability can be mitigated by configuring the readTimeout option.

Traefik is an HTTP reverse proxy and load balancer. Versions prior to 2.11.6, 3.0.4, and 3.1.0-rc3 have a vulnerability that allows bypassing IP allow-lists via HTTP/3 early data requests in QUIC 0-RTT handshakes sent with spoofed IP addresses. Versions 2.11.6, 3.0.4, and 3.1.0-rc3 contain a patch for this issue. No known workarounds are available.

Traefik is a golang, Cloud Native Application Proxy. When a HTTP request is processed by Traefik, certain HTTP headers such as X-Forwarded-Host or X-Forwarded-Port are added by Traefik before the request is routed to the application. For a HTTP client, it should not be possible to remove or modify these headers. Since the application trusts the value of these headers, security implications might arise, if they can be modified. For HTTP/1.1, however, it was found that some of theses custom headers can indeed be removed and in certain cases manipulated. The attack relies on the HTTP/1.1 behavior, that headers can be defined as hop-by-hop via the HTTP Connection header. This issue has been addressed in release versions 2.11.9 and 3.1.3. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Traefik (pronounced traffic) is an HTTP reverse proxy and load balancer. There is a vulnerability in Traefik that allows the client to provide the X-Forwarded-Prefix header from an untrusted source. This issue has been addressed in versions 2.11.14 and 3.2.1. Users are advised to upgrade. There are no known workarounds for this vulnerability.
