CVE-2026-112006: OpenTelemetry opentelemetry-exporter-otlp-proto-http TLS certificate validation bypass

CVE-2026-112006 · Severity: medium · CVSS 6.5 · Published 2026-10-18

OpenTelemetry's OTLP HTTP exporter is a library that sends telemetry data (traces, metrics, logs) from applications to a central collector. A vulnerability allows empty certificate configuration variables to disable TLS verification entirely, letting attackers intercept network traffic and impersonate the collector. This enables theft or modification of exported telemetry including sensitive headers and authentication credentials.

Vendors: Opentelemetry.

How to fix

Fixed in: 1.45.0

Technical details

The exporter improperly validates certificate configuration: when OTEL_EXPORTER_OTLP_CERTIFICATE environment variables are set to empty strings, TLS verification is disabled instead of being enforced with defaults. An attacker on the network can perform man-in-the-middle attacks to read or modify exported traces, metrics, logs, and headers without the application detecting the compromise. The fix is available in version 1.45.0.
