- Mitigation guidance
- To prevent unauthorized data injection, configure the `githubreceiver` with a robust secret for HMAC validation. Ensure that the `Secret` field is never left empty in the `githubreceiver` configuration. If the `githubreceiver` is not essential for your deployment, disable or remove the component to eliminate this attack vector. A restart of the OpenTelemetry Collector may be required for configuration changes to take effect.
