CVE-2026-45685 PUBLISHED

OpenTelemetry eBPF Instrumentation: MongoDB parser panics on malformed wire messages

Assigner: GitHub_M
Reserved: 13.05.2026 Published: 02.06.2026 Updated: 02.06.2026

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. From version 0.1.0 to before version 0.9.0, malformed MongoDB wire messages can trigger uncaught panics in the MongoDB TCP parser, allowing a remote unauthenticated attacker to crash the telemetry agent and cause a denial of service. The parser operates on raw attacker-controlled network payloads before the input is fully validated, so a single crafted message can terminate telemetry collection for the affected process or node. This issue has been patched in version 0.9.0.
