go.etcd.io/etcd Authentication Bypass

etcd versions 3.2.x before 3.2.26 and 3.3.x before 3.3.11 are vulnerable to an improper authentication issue when role-based access control RBAC is used and client-cert-auth is enabled. If an etcd client server TLS certificate contains a Common Name CN which matches a valid RBAC username, a remot...

Denial of Service (DoS)

Overview grpc/grpc-swift is a Swift language implementation of gRPC. Affected versions of this package are vulnerable to Denial of Service DoS via reachable assertion, due to an incorrect logic when handling GOAWAY frames. Details Denial of Service DoS describes a family of attacks, all aimed at...

Unbounded memory usage on exposed HTTP/2 (non-gRPC) endpoints

Impact The net/http Go package has a reported vulnerability tracked under CVE-2021-44716 which allows attacker controlled HTTP/2 requests to trigger unbounded memory usage in HTTP/2 endpoints. gRPC endpoints are not vulnerable as they rely on their own HTTP/2 implementation instead of the net/htt...
