Resource limit bypass via message compression

Impact If this library is used in tandem with the permessage-deflate extension, a WebSocket server or client can be made to accept messages that are larger than the configured maximum message size. This is because this limit is checked against the message frames' length headers, which give the si...

Memory exhaustion in HTTP header parser

Impact If this library is used to implement a WebSocket server on top of a TCP server rather than an HTTP server or framework using the WebSocket::Driver.server method, or, if it is used to complement a WebSocket client, then a peer can make a single connection consume an unbounded amount of memo...

Origin Validation Error

Overview Affected versions of this package are vulnerable to Origin Validation Error via the cookies parameter, which is processed by connectandsendrequest in client.py. An attacker who can control a redirect on a request that passes cookies on a per-request basis can expose data from those...

quic-go: HTTP/3 QPACK Trailer Expansion Memory Exhaustion

Summary An attacker can cause excessive memory allocation in quic-go's HTTP/3 client and server implementations by sending a QPACK-encoded HEADERS frame that decodes into a large trailer field section with many unique field names and/or large values. The implementation builds an http.Header for t...

A remot...

google.golang.org/grpc/grpc-go: google.golang.org/grpc/authz: gRPC-Go: Authorization bypass due to improper HTTP/2 path validation

A flaw was found in gRPC-Go, the Go language implementation of gRPC. This vulnerability, an authorization bypass, is caused by improper input validation of the HTTP/2 :path pseudo-header. A remote attacker can exploit this by sending raw HTTP/2 frames with a malformed :path that omits the mandato...
