CVE-2026-52879 Klever-Go: Unbounded goroutine spawn on direct-message ingress enables peer-driven DoS

Klever-Go is the Go implementation of the Klever blockchain protocol. In versions 1.7.14 through 1.7.17, the direct-message ingress handler spawns a new goroutine for every incoming direct message before the processor-level antiflood layer makes any admission decision, with no semaphore, throttle...

CVE-2026-70616

CVE-2026-70616 affects boringproxy 0.10.0. The vulnerability allows an authenticated user to cause resource exhaustion on the server by sending requests to GET /loading with attacker-supplied id values. The handler performs no map-lookup validation and blocks on a nil channel, with no timeout, ca...

SUSE CVE-2026-52814

Gogs is an open source self-hosted Git service. Prior to 0.14.3, the Gogs built-in Go SSH server is vulnerable to an unauthenticated, asymmetric Denial of Service DoS attack. The application accepts inbound TCP connections and passes them to golang.org/x/crypto/ssh.NewServerConn inside a new...

GHSA-6VCH-Q96H-7GC3 etcd: `tlsListener.acceptLoop` spawns unbounded handshake goroutines with no deadline

Impact What kind of vulnerability is it? Who is impacted? A network attacker who can reach an etcd TLS listener can open many TCP connections and never send a ClientHello. Each connection spawns a goroutine in the etcd server process that blocks indefinitely inside tls.Conn.Handshake, and each is...

Uncontrolled Resource Consumption

github.com/spectolabs/hoverfly is vulnerable to Uncontrolled Resource Consumption Denial of Service. The vulnerability is due to the use of http.DefaultClient without a configured timeout for remote post-serve actions, which allows an attacker to trigger requests to a non-responsive endpoint,...

Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of timeout configuration in the http.DefaultClient used for remote post-serve actions. An attacker can exhaust system memory and crash the process by registering a...

CVE-2026-48708

OliveTin is affected by a race condition in the template engine. In versions up to 3000.0.0, a single shared text/template.Template instance (tpl) is used across all goroutines, and actions perform tpl.Parse(source) followed by t.Execute() without synchronization. Under concurrent ExecRequests, t...

GHSA-HF2G-6J7H-98WG klever-go: Unbounded goroutine spawn on direct-message ingress enables peer-driven DoS

Summary networkMessenger.directMessageHandler in network/p2p/libp2p/netMessenger.go spawns a fresh goroutine for every incoming direct message before the antiflood layer makes an admission decision. There is no semaphore, throttler, or bound on concurrent in-flight spawns. A single connected libp...
