Overview
Affected versions of this package are vulnerable to Exposure of Private Personal Information to an Unauthorized Actor in the ProxyConfig constructor in lib/internal/http.js, which stores the full proxy URL including any embedded username and password and surfaces it in ERR_PROXY_TUNNEL error messages. When proxy tunnel establishment fails, the resulting error carries the credentials embedded in the proxy URL, exposing them to anyone able to read the process's error output, stack traces, logs, or diagnostics. Exposure requires the proxy to be configured with credentials embedded in its URL and occurs only on a tunnel establishment failure, reaching only parties with access to that error output or downstream log and diagnostic sinks.
