CVE-2026-81871

A flaw was found in OpenTelemetry-Go, specifically within its gRPC log exporter. This vulnerability allows a network attacker to bypass the intended private Certificate Authority (CA) pinning and mutual Transport Layer Security (TLS) configurations. The issue arises because the environment-only TLS path incorrectly uses system-trusted certificates instead of the application's configured client certificates. This bypass enables an attacker to intercept and spoof the collector connection, potentially leading to the unauthorized reading or alteration of sensitive log telemetry.

CVE-2026-81872

A flaw was found in the OpenTelemetry-Go `BatchingProcessor` component. A remote attacker can exploit this by sending a high volume of log emissions, which can fill the asynchronous export buffer. This causes the processor to enter a tight CPU loop, repeatedly retrying to export logs without proper waiting mechanisms. The consequence is the exhaustion of CPU resources, leading to a degradation or denial of service (DoS) in the affected application.

A remote attacker can exploit this by sending a high volume of log emissions, which can fill the asynchronous export buffer.

The consequence is the exhaustion of CPU resources, leading to a degradation or denial of service (DoS) in the affected application.",
