excessive data transfer due to misuse of the WebSocket ping/pong feature.\n\n2.10 Pulsar WebSocket Proxy users should upgrade to at least 2.10.5.\n2.11 Pulsar WebSocket Proxy users should upgrade to at least 2.11.2.\n3.0 Pulsar WebSocket Proxy users should upgrade to at least 3.0.1.\n3.1 Pulsar WebSocket Proxy users are unaffected.\nAny users running the Pulsar WebSocket Proxy for 2.8, 2.9, and earlier should upgrade to one of the above patched versions.", "references": [ { "reference_url": "https://api.first.org/data/v1/epss?cve=CVE-2023-37544", "reference_id": "", "reference_type": "",
