CVE-2026-59818 etcd: gRPC client listener does not enforce `--client-crl-file` certificate revocation

etcd is a distributed key-value store for the data of a distributed system. Prior to 3.5.32 and 3.6.13, when etcd is configured with --listen-client-http-urls to split HTTP and gRPC client endpoints onto separate listeners, the --client-crl-file Certificate Revocation List is not enforced on the...

CVE-2026-59818

CVE-2026-59818 affects etcd (distributed key-value store). Prior to versions 3.5.32 and 3.6.13, when etcd uses separate HTTP and gRPC client listeners, the --client-crl-file CRL is not enforced on the gRPC listener, letting a revoked-certificate client authenticate over gRPC. The issue is fixed i...

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...

CVE-2026-54061 Dgraph Alpha group stores can be replaced via unauthenticated external snapshot import

Dgraph is an open source distributed GraphQL database. Prior to version 25.3.5, Dgraph Alpha exposes the RPCs used for external snapshot import on the public gRPC port :9080 without authentication or authorization. As a result, an unauthenticated network client can open StreamExtSnapshot and send...

Amazon Linux 2 : nginx, --advisory ALAS2NGINX1-2026-014 (ALASNGINX1-2026-014)

The version of nginx installed on the remote host is prior to 1.30.3-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2NGINX1-2026-014 advisory. NGINX Plus and NGINX Open Source have a vulnerability in the ngxhttpproxyv2module and ngxhttpgrpcmodule modules. This...

nginx: NGINX: Arbitrary code execution or Denial of Service via heap-based buffer overflow with crafted HTTP/2 headers

A flaw was found in NGINX. When NGINX is configured to proxy HTTP/2 traffic using the ngxhttpproxyv2module or ngxhttpgrpcmodule with specific settings, a remote, unauthenticated attacker can send specially crafted large headers. This can trigger a heap-based buffer overflow, leading to a restart ...
