Information disclosure in Open-Telemetry Opentelemetry-Ebpf-Instrumentation
CVE-2026-45679
OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, OBI exports raw Redis error text as the span status message. Because Redis error replies can contain attacker-controlled or sensitive values, this behavior can exfiltrate tokens, PII, or other confidential input into telemetry backends and inject untrusted text into downstream analysis systems. This issue has been patched in version 0.9.0.
