This vulnerability allows information disclosure when invalid proxy configurations trigger error handling routines that fail to redact authentication details. Under these conditions, the application outputs raw proxy URLs containing embedded usernames and passwords to error streams and log services. An unauthorized actor with access to system logs, monitoring outputs, or crash reports can retrieve these credentials to access restricted proxy resources.\nThis vulnerability is rated as Moderate impact because sensitive proxy authentication credentials may be exposed to unauthorized observers through application output channels, yet exploitation does not grant direct system compromise or remote code execution. In typical Red Hat Enterprise Linux and OpenShift container deployments, Node.js applications configured with erroneous proxy settings can print intact secrets into standard error streams, shared container logs, or log collectors. Exposure is limited to environments where proxy authentication is configured and specific configuration errors occur during proxy initialization.",
