Linux Distros Unpatched Vulnerability : CVE-2026-100663

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Netty's HTTP/3 codec io.netty:netty-codec-http3 from 4.2.2.Final through 4.2.17.Final does not special- case HTTP/1 CONNECT authority-form request-targets when...

BIT-ENVOY-2026-73547 Envoy ext_authz: request `:path` pseudoheader dereferenced w/o null check

Envoy is an open source edge and service proxy designed for cloud-native applications. Prior to 1.36.10, 1.37.6, 1.38.4, and 1.39.1, Envoy's extauthz filter assumes that a request contains a :path pseudoheader when applying queryparameterstoset or queryparameterstoremove from an authorization...

curl: curl: Unauthorized access due to improper HTTP proxy connection reuse

A flaw was found in curl. This vulnerability allows curl to wrongly reuse an existing HTTP proxy connection when performing a CONNECT request to a server, even if the new request uses different authentication credentials for the HTTP proxy. This improper connection reuse could lead to an attacker...

CVE-2026-100663

Netty's HTTP/3 codec io.netty:netty-codec-http3 from 4.2.2.Final through 4.2.17.Final does not special-case HTTP/1 CONNECT authority-form request-targets when converting HTTP/1 messages to HTTP/3 in HttpConversionUtil.toHttp3Headers. The authority-form target e.g., "CONNECT trusted.example:443" i...

netty: io.netty/netty-handler-proxy: Netty: HTTP Header Injection via HttpProxyHandler Disabled Validation

A flaw was found in Netty. The HttpProxyHandler component, which handles HTTP CONNECT requests, does not properly validate user-provided outbound headers. This allows an attacker to inject arbitrary HTTP headers into the CONNECT request sent to the proxy server. This could lead to unexpected...

Linux Distros Unpatched Vulnerability : CVE-2026-85720

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - The AsyncHttpClient AHC library allows Java applications to easily execute HTTP requests and asynchronously process HTTP responses. From 2.0.0 until 2.16.1 and...

CVE-2026-93567 Io.netty/netty-codec-http2: http/1 authority-form connect is translated to malformed http/2 connect with host-controlled :authority

A flaw was found in Netty's HTTP/2 codec. When converting HTTP/1 CONNECT requests to HTTP/2, the component incorrectly uses the Host header instead of the CONNECT authority-form request-target for the tunnel authority. A remote attacker can exploit this by supplying a different Host header, leadi...

GHSA-XR57-GCX8-52HF AsyncHttpClient sends origin credentials to the proxy on the plaintext CONNECT request

Impact When a request uses an HTTP proxy to reach an HTTPS origin, the client opens the tunnel with a plaintext CONNECT sent to the proxy before any TLS exists. On affected versions the origin's preemptive credentials were added to that CONNECT. A Basic realm sent Authorization: Basic...
