Red Hat has released updated packages (tempo3.0-3.0.3-0.3.hum1) that fix this vulnerability. Users should apply this update to their Red Hat Hardened Images RPMs to remediate the issue. No additional mitigations are specified by Red Hat. Patch status is confirmed by the vendor advisory.
Description
A vulnerability (CVE-2026-81871) was found in OpenTelemetry-Go's gRPC log exporter used in Red Hat Hardened Images RPMs. It allows a network attacker to bypass private Certificate Authority pinning and mutual TLS configurations due to improper use of system-trusted certificates instead of configured client certificates. This enables interception and spoofing of the collector connection, potentially leading to unauthorized reading or alteration of sensitive log telemetry data. Red Hat has issued an update including tempo3.0-3.0.3-0.3.hum1 packages to address this issue.
