CVE-2026-93569

CVE-2026-93569 affects the netty-codec-http2 component of the Netty library. The vulnerability occurs during the translation of HTTP/1 absolute-form requests to HTTP/2: a Host header mismatch is incorrectly propagated into the HTTP/2 :authority pseudo-header, overriding the authority specified in...

CVE-2026-93569 Io.netty/netty-codec-http2: http/1 absolute-form host mismatch is translated to http/2 :authority, overriding the request-target authority

A flaw was found in Netty. A remote unauthenticated attacker can exploit a vulnerability in Netty's HTTP/1 to HTTP/2 conversion process. When an HTTP/1 request includes both an absolute-form request-target and a conflicting Host header, Netty incorrectly prioritizes the Host header for the HTTP/2...

CVE-2026-93567

Io.netty/netty-codec-http2 is vulnerable when an HTTP/1 authority-form CONNECT request is translated into a malformed HTTP/2 CONNECT frame, resulting in a Host-controlled :authority pseudo-header. This is a network-reachable issue requiring no privileges or user interaction, with a CVSS 3.1 base ...

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...

A remote attacker can exploit this by supplying a different Host header, leadi...

CVE-2026-93568

A flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/2 or HTTP/3 Extended CONNECT requests. Netty's HTTP-object conversion path incorrectly processes these requests as regular HTTP/1.1 CONNECT requests, leading to a loss of critical...

CVE-2026-93566

A flaw was found in Netty. A remote attacker could exploit this by sending a specially crafted HTTP request that includes control characters within the chunk-size line. This bypasses the intended strict validation, allowing the attacker to inject arbitrary HTTP requests. This vulnerability can le...

CVE-2026-93566

Netty (io.netty/netty-codec-http) is vulnerable to HTTP request smuggling due to a flaw in chunk-size line validation. The method HttpObjectDecoder#checkChunkExtensions only invokes the strict validator HttpChunkLineValidatingByteProcessor when a chunk extension (;) is present. When no extension ...
