1. CVE-2026-119566 Prometheus through 3.15.1 Credential Leak via remote_write Cross-Host Redirects

   Published 2026-10-30

   Medium·CVSS 6.3 EPSS 0.20%

   Prometheus through 3.15.1 contains a credential leak vulnerability that allows attackers to capture Azure AD or Google IAM bearer tokens by redirecting remote_write requests to another host. Attackers controlling the remote-write endpoint or a redirecting server can return a 3xx...

2. CVE-2026-116591 compress zstd: Panic on two-block frames

   Published 2026-10-26

   High·CVSS 8.7 EPSS 0.33%

   compress provides various compression algorithms. Prior to 1.20.2, the zstd DecodeAll and streaming decoder paths can panic when a crafted two-block frame reaches huff0.ReadTable with an FSE normalized count of 32768 that readNCount stores in int16 as -32768. The wrapped count al...

3. CVE-2026-19444 Kubernetes kubectl cp path traversal on Windows allows arbitrary file writes

   Published 2026-09-28

   gRPC-Go is the Go language implementation of gRPC. Prior to 1.82.2 and 1.83.2, servers created with xds.NewGRPCServer() allow internal/transport/http2_server.go to accept an RPC containing neither the :authority header nor the Host header, while RouteAndProcess in internal/xds/se...

5. CVE-2026-84304 gRPC-Go: Heap Memory Exhaustion (OOM) via HTTP/2 DATA Frame Fragmentation

   Published 2026-09-01

   High·CVSS 8.7 EPSS 0.61%

   gRPC-Go is the Go language implementation of gRPC. Prior to 1.83.1, internal/transport/transport.go stores each fragmented HTTP/2 DATA frame as a separate recvMsg in recvBuffer, so millions of one-byte frames can consume disproportionate heap memory even when payload bytes remain...
