What is CVE-2026-45685?

The eBPF Instrumentation of OpenTelemetry is susceptible to a vulnerability that allows for denial of service through malformed MongoDB wire messages. Versions prior to 0.9.0 have an issue where these malformed messages can lead to uncaught panics in the MongoDB TCP parser. This vulnerability enables a remote attacker to crash the telemetry agent without authentication, disrupting telemetry collection for the affected processes or nodes. The input is processed before proper validation, which increases the risk of denial of service. This vulnerability has been addressed in version 0.9.0.

Affected Version(s)

opentelemetry-ebpf-instrumentation >= 0.1.0, < 0.9.0
