GHSA-4FWH-WRM6-97XM Klever-Go: Unauthenticated WebSocket /subscribe: no read-size limit, no connection cap, permissive origin -> remote node memory/goroutine exhaustion (DoS)

Summary The unauthenticated WebSocket endpoint GET /subscribe is registered open: true by default config/node/api.yaml and lets a remote, unauthenticated client exhaust the node's memory and goroutines. Because the REST API runs IN-PROCESS with the node — network/api/api.go Start... ends with...

CVE-2026-86065 Klever-Go: Unauthenticated WebSocket /subscribe: no read-size limit, no connection cap, permissive origin -> remote node memory/goroutine exhaustion (DoS)

Klever-Go is the Go implementation of the Klever blockchain protocol. Prior to 1.7.20, the default-open GET /subscribe endpoint in network/api/websocket/routes.go accepts unauthenticated WebSocket clients with permissive origin handling, does not call SetReadLimit to bound message size, and has n...

CVE-2026-11993

Mattermost versions 11.9.x ≤ 11.9.0 , 11.8.x ≤ 11.8.4 , 11.7.x ≤ 11.7.7 , and 10.11.x ≤ 10.11.22 are affected by a resource-exhaustion flaw in the file content indexing subsystem. The root cause is a failure to properly enforce the limit of concurrent files being processed and to handle failed fi...

CVE-2026-73500

A flaw was found in etcd, a distributed key-value store. A remote attacker can exploit this by opening numerous TCP connections to an etcd TLS listener without completing the TLS handshake. This action causes the tlsListener.acceptLoop to spawn an unbounded number of goroutines, which consume...

GO-2026-6107 Unbounded TLS handshake goroutines in go.etcd.io/etcd/client/pkg/v3

In go.etcd.io/etcd/client/pkg/v3 before 3.5.33, 3.6.14, and 3.7.1, TLS handshakes on listeners created by NewTLSListener do not enforce a handshake deadline. An unauthenticated network attacker who connects to an etcd TLS listener without sending a ClientHello causes a goroutine and a tracking ma...
