CVE-2026-55180: pnpm: Repository config can expand victim environment secrets into registry requests before scripts run

June 26, 2026

pnpm and pacquet expanded ${ENV_VAR} placeholders from repository-controlled .npmrc and pnpm-workspace.yaml into registry request destinations and registry credentials. A malicious repository could cause dependency resolution to send victim environment secrets to an attacker-selected registry before lifecycle scripts run.
