netty: io.netty/netty-codec-http: Netty: HTTP Request Smuggling due to improper handling of conflicting HTTP/1.0 headers

A flaw was found in Netty's HttpObjectDecoder. A remote attacker can exploit this by sending a specially crafted HTTP/1.0 request that includes both Transfer-Encoding: chunked and Content-Length headers. While Netty correctly strips the conflicting Content-Length header for HTTP/1.1 messages, thi...

netty: io.netty/netty-codec-http: io.netty/netty-codec-http2: Netty: Denial of Service via unbounded memory allocation in HTTP content decompression

A flaw was found in Netty. A remote attacker can bypass the configured decompression limit in the HttpContentDecompressor by sending a specially crafted compressed payload using Brotli br, Zstandard zstd, or Snappy content encodings. This can lead to unbounded memory allocation, resulting in an...

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...

github.com/getkin/kin-openapi: kin-openapi: Denial of Service via unsupported HTTP methods on static paths

A flaw was found in kin-openapi. An unauthenticated remote attacker can cause a Denial of Service DoS by sending requests with unsupported or non-canonical HTTP methods to an existing static path. Because the application encounters an unhandled panic before authentication is evaluated, these...

undici: undici: Denial of Service via failed HTTP/2 WebSocket handshake

A flaw was found in undici. A malicious remote server can cause a Denial of Service DoS by returning an invalid handshake response when a client attempts to establish a WebSocket connection over HTTP/2. The client mishandles the failed connection setup and leaves the underlying network stream ope...

Security update for docker-stable

This update for docker-stable fixes the following issues: CVE-2026-33186: google.golang.org/grpc: authorization bypass due to improper validation of the HTTP/2 :path pseudo- header bsc1260279. CVE-2026-33814: golang.org/x/net/http2: infinite loop in HTTP/2 transport when given bad...

io.netty/netty-codec-http2: Netty: Denial of Service via HTTP/2 DATA frame memory leak

A flaw was found in Netty, a network application framework. A remote, unauthenticated attacker can exploit this vulnerability by sending specially crafted HTTP/2 DATA frames to applications that use Netty and have HTTP/2 content decompression enabled. This can lead to memory exhaustion, causing t...

io.netty/netty-codec-http: Netty: Denial of Service via SPDY SETTINGS frame processing

A flaw was found in Netty, a network application framework. A remote attacker, by sending a specially crafted SPDY/3.1 SETTINGS frame, could cause the SPDY SETTINGS decoder to create a large number of map entries. This excessive processing and memory allocation can lead to a denial of service DoS...

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...

netty: io.netty/netty-codec-http: Netty: Denial of Service via memory exhaustion in SPDY-to-HTTP codec

A flaw was found in Netty. A remote attacker can exploit a vulnerability in the SpdyHttpDecoder handler of Netty's SPDY-to-HTTP codec. When processing a client-initiated SYNSTREAM frame, the decoder fails to release allocated memory if the stream is reset or content limits are exceeded. This...

io.netty/netty-codec-http: Netty: Memory exhaustion in netty-codec-http (decompression bomb)

A flaw was found in the Netty netty-codec-http component. A remote attacker can send HTTP requests containing highly compressed data. The HTTP decoder in netty-codec-http fails to properly limit the decompression of this content, causing the system to consume excessive memory. This can lead to...
