CVE-2026-59900

Netty CVE-2026-59900 affects the HTTP/2→HTTP/1.x translation in Netty’s HTTP/2-to-HTTP/1.x codec (Http2StreamFrameToHttpObjectCodec and InboundHttp2ToHttpAdapter). When an HTTP/2 client sends both the :authority pseudo-header and a literal Host header in the same HEADERS frame, the translator may...

CVE-2026-59900 Netty codec-http2: Lack of Host Header Deduplication in HTTP/2→HTTP/1.x Translation Leads to Request Routing Bypass

Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, Netty's HTTP/2-to-HTTP/1.x translation layer Http2StreamFrameToHttpObjectCodec and InboundHttp2ToHttpAdapter fails to deduplicate or validate Host headers when an HTTP/2 client...

CVE-2026-59919 Netty: HAProxy V1 Protocol CRLF Injection via AF_UNIX Address

Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.136.Final and 4.2.16.Final, Netty's HAProxy encoder HAProxyMessageEncoder writes AFUNIX source and destination socket addresses into the HAProxy V1 text protocol without validating them for CRLF...

CVE-2026-59920

Netty CVE-2026-59920 concerns the STOMP framing path: the STOMP encoder StompSubframeEncoder intentionally does not escape header values for CONNECT and CONNECTED frames, allowing raw newline characters to be written to the wire. This creates a header-injection risk, because a header value contai...

EUVD-2026-50424

Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.136.Final and 4.2.16.Final, Netty's STOMP encoder StompSubframeEncoder does not escape or validate header values in CONNECT and CONNECTED frames, so raw newline \n characters in a header value are...

CVE-2026-59920 Netty: STOMP CONNECT Frame Header Injection

Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.136.Final and 4.2.16.Final, Netty's STOMP encoder StompSubframeEncoder does not escape or validate header values in CONNECT and CONNECTED frames, so raw newline \n characters in a header value are...

io.netty/netty-codec-http: Netty: CRLF Injection via Multipart Filename in Netty HttpPostRequestEncoder

A flaw was found in Netty's HttpPostRequestEncoder, a widely used Java networking library component responsible for constructing multipart HTTP request bodies. The issue arises because user-supplied filenames and field names are directly embedded into Content-Disposition MIME headers without any...

netty: io.netty/netty-codec-http: Netty: Denial of Service via SPDY header decompression amplification

A flaw was found in Netty, a network application framework. A remote attacker could exploit a vulnerability in the SPDY header decoding process. By sending a specially crafted, small compressed header block, the attacker can cause it to expand significantly during decompression, leading to...

io.netty/netty-codec-http2: Netty: Improper header neutralization in netty-codec-http2

A flaw was found in Netty's netty-codec-http2 component. The HTTP/2 encoder does not properly handle special characters in HTTP headers. This vulnerability allows a remote attacker to craft specific HTTP/2 requests, leading to HTTP response splitting and header injection attacks. Such attacks can...

io.netty/netty-codec-http: Netty: Security control bypass allows unauthorized requests via null origin header

A flaw was found in Netty, a network application framework. A remote attacker can bypass security controls in the CorsHandler component by sending a specially crafted request with a null origin header. This bypasses the intended access restrictions, allowing unauthorized requests to reach the...

CVE-2026-18174

The CVE-2026-18174 entry concerns @fastify/forwarded. In versions before 3.0.2, the X-Forwarded-For parser trims only spaces when entries are comma-separated and does not strip horizontal tabs. As a result, an entry padded with a tab retains a literal tab in the resolved client IP string, potenti...

EUVD-2026-50332

@fastify/forwarded resolves client addresses from the X-Forwarded-For header. In versions before 3.0.2, when the header contains two or more comma separated entries, the parser trims only space characters and does not strip horizontal tabs, even though RFC 7230 defines optional whitespace as both...

CVE-2026-56390

GNU Bison improperly handles grammar‑defined output paths. Grammar directives such as %output and %header allow specifying file paths, which are accepted without restriction and override caller‑supplied output options. When processing attacker-supplied grammar, this behavior allows directing...

CVE-2026-65100

Apache Traffic Server updates the HTTP/2 HPACK dynamic table before confirming the header block encoded successfully, so an encode failure leaves the encoder out of sync with the peer decoder and corrupts subsequent header blocks on the connection. This issue affects Apache Traffic Server: from...
