  "title": "opentelemetry-cpp: OTLP HTTP exporters read unbounded HTTP response",
  "description": "OpenTelemetry-cpp is the C\u002B\u002B implementation of OpenTelemetry. Prior to release 1.27.0, the OTLP HTTP exporters (traces/metrics/logs) read the full HTTP response into an in-memory vector of bytes without a size cap. This is exploitable for memory exhaustion when the configured collector endpoint is attacker-controlled (or a network attacker can MITM the exporter connection). This vulnerability is fixed in opentelemetry-cpp release 1.27.0.",
