Executive Summary

This vulnerability affects the baseline-browser-mapping library versions 2.x before 2.11.0. When invalid or conflicting input parameters are provided, the library calls process.exit() instead of throwing an error, causing the application to terminate immediately. This leads to a denial of service as the process stops unexpectedly.

Impact Analysis

If you use the affected versions of baseline-browser-mapping, an attacker could exploit this by providing malicious input to crash your application. This results in downtime, loss of service, and potential disruption to users relying on your application.

Mitigation Strategies

Update baseline-browser-mapping to version 2.11.0 or later to address the process.exit() issue causing denial of service.
