Error Trace

Vulnerability information

New Relic’s .NET error collection captures information about uncaught exceptions and sends them to New Relic. If High-security mode is enabled, the agent should not capture details of the error messages. This release fixes the agent for error traces and error events so that the error message is not sent to New Relic when High-security mode is enabled.

Mitigating factors


Disable error collection in the agent configuration or ignore specific exceptions in the configuration.
