GHSA-RJ37-6J9X-74Q6 SwiftNIO NIOHTTP1: HTTPDecoder accepts unbounded HTTP/1 header blocks, enabling remote DoS

Summary The HTTPDecoder in NIOHTTP1 enforces no limit on the total size of an HTTP/1 message's header block or on the number of header fields per message. A remote peer can submit an arbitrary number of small, valid headers in a single request and have them all accumulated into the resulting...

SwiftNIO HTTP/2: HTTP/2-to-HTTP/1 Request Smuggling via unvalidated :path pseudo-header in HTTP2ToHTTP1Codec

swift-nio-http2's HTTP/2-to-HTTP/1.1 codec HTTP2FramePayloadToHTTP1ServerCodec / HTTP2ToHTTP1ServerCodec did not validate pseudo-header values for control characters before placing them into the translated HTTP/1.1 message. A remote attacker could send an HTTP/2 request containing CR \r, LF \n, o...

swift-nio-http2's HTTP/2-to-HTTP/1.1 codec HTTP2FramePayloadToHTTP1ServerCodec / HTTP2ToHTTP1ServerCodec did not validate pseudo-header values for control characters before placing them into the translated HTTP/1.1 message. A remote attacker could send an HTTP/2 request containing CR r, LF , or N...

SwiftNIO: Out-of-bounds write via ByteBuffer index and length UInt32 overflow

A program using swift-nio is vulnerable to a potential out-of-bounds write when attacker-controlled index or length values exceeding UInt32.max are passed to some ByteBuffer methods. This affects all swift-nio versions from 1.0.0 to 2.99.0. It is fixed in 2.100.0 and later releases...

GHSA-773G-X274-8QMF SwiftNIO Extras vulnerable to improper detection of complete HTTP body decompression

SwiftNIO Extras provides a pair of helpers for transparently decompressing received HTTP request or response bodies. These two objects HTTPRequestDecompressor and HTTPResponseDecompressor both failed to detect when the decompressed body was considered complete. If trailing junk data was appended ...

GHSA-7FJ7-39WJ-C64F SwiftNIO vulnerable to Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')

NIOHTTP1 and projects using it for generating HTTP responses, including SwiftNIO, can be subject to a HTTP Response Injection attack. This occurs when a HTTP/1.1 server accepts user generated input from an incoming request and reflects it into a HTTP/1.1 response header in some form. A malicious...

SwiftNIO vulnerable to HTTP request smuggling using malformed Transfer-Encoding header

Impact Affected SwiftNIO systems are vulnerable to request smuggling attacks, in which they parse a given HTTP message differently from other network parties, potentially seeing a different number of requests than other servers. This can lead to failures of authentication, routing, and other...
