From version 3.0.0 until 3.1.1, the build-time server-only module guard did not treat src/params.js as a client entry point even though parameter matchers can run in the browser. Server-only modules imported through src/params.js could consequently enter the client bundle, where statically replaced private environment values or other server secrets could be exposed. This issue is fixed in 3.1.1."}], "source": {"advisory": "GHSA-m9j8-jcmv-hp69", "discovery": "UNKNOWN"}}}}
