CVE-2026-50018

Hoverfly (open source API simulation tool) prior to version 1.12.8 is vulnerable to denial of service via a goroutine leak in its remote post-serve actions . The root cause is the use of http.DefaultClient without any timeout configuration: when the remote endpoint is unreachable or intentionally...

CVE-2026-50018 Hoverfly: Denial of Service via Goroutine Leak in Remote Post-Serve Actions

Hoverfly is an open source API simulation tool. Prior to version 1.12.8, remote post-serve actions use http.DefaultClient without any timeout configuration. When the remote endpoint is unreachable or intentionally slow accepts TCP connection but never responds, each triggered proxy request spawns...

Allocation of Resources Without Limits or Throttling

Overview github.com/containerd/containerd/pkg/cri/server is an industry-standard container runtime with an emphasis on simplicity, robustness and portability. It is available as a daemon for Linux and Windows, which can manage the complete container lifecycle of its host system: image transfer an...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the drainExecSyncIO function in internal/cri/server/containerexecsync.go, pkg/cri/server/containerexecsync.go, and pkg/cri/sbserver/containerexecsync.go. An attacker can cause...

containerd: CRI ExecSync Goroutine Leak Leads to Node-Level Denial of Service

Impact A bug in containerd's CRI ExecSync implementation allows exec probes and lifecycle hooks with background child processes to keep containerd's stdio-drain goroutines indefinitely blocked. Because the I/O drain phase lacks a default timeout or context cancellation handling, repeated ExecSync...
