Summary
A vulnerability in pnpm package manager prior to versions 10.34.2 and 11.5.3 expands ${ENV_VAR} placeholders from repository-controlled .npmrc and pnpm-workspace.yaml files into registry request destinations and credentials. A malicious repository can send victim environment secrets to an attacker-selected registry before lifecycle scripts run.
Risk Assessment
The organization risks leaking sensitive environment variables (e.g., tokens, API keys) to an unauthorized registry, potentially leading to system and data compromise.
Recommendation
Immediately update pnpm to version 10.34.2 or 11.5.3, depending on the branch in use, to remediate the vulnerability.
Original NVD description (English source)
pnpm is a package manager. Prior to 10.34.2 and 11.5.3, 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. This vulnerability is fixed in 10.34.2 and 11.5.3.
