opentelemetry-cpp: OTLP HTTP exporters read unbounded HTTP response
CVE-2026-44967 is fixed in opentelemetry-cpp on 1 platform by DEBIAN-CVE-2026-44967 (version 1.28.0-1), released June 12, 2026. It is not reported as exploited. Patch Radar priority: Routine.
OpenTelemetry-cpp is the C++ 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.
