Denial of Service Vulnerability in baseline-browser-mapping by Web Platform DX

CVE-2026-45819

What is CVE-2026-45819?

The baseline-browser-mapping library version 2.x prior to 2.11.0 contains a vulnerability where invalid or conflicting input parameters lead to immediate process termination by calling process.exit(), potentially resulting in a denial of service. This behavior compromises the stability of applications utilizing the library. The issue has been addressed in version 2.11.0, where the inappropriate process.exit() calls were replaced with appropriate error handling mechanisms.
