Hi, The following vulnerability was published for opentelemetry-cpp. CVE-2026-44967[0]: | 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. https://github.com/open-telemetry/opentelemetry-cpp/security/advisories/GHSA-5qhm-4rfp-qqvj https://github.com/open-telemetry/opentelemetry-cpp/issues/3958 https://github.com/open-telemetry/opentelemetry-cpp/pull/4078 If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
