CVE-2026-115716 Nov 3, 2026 Source: Vendor
Allocation of Resources Without Limits or Throttling (CWE-770) in APM Server can lead to denial of service via Oversized Serialized Data Payloads (CAPEC-231). An attacker who can send OpenTelemetry (OTLP) data to APM Server over HTTP can cause APM Server to exhaust its memory and terminate. This stops the intake of APM and OpenTelemetry data until APM Server restarts.
