pnpm vulnerable to Command Injection via environment variable substitution

CVE-2025-69262GHSA-2phv-j68v-wwqx

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (pnpm 10.27.0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Summary A command injection vulnerability exists in pnpm when using environment variable substitution in .npmrc configuration files with tokenHelper settings. An attacker who can control environment variables during pnpm operations could achieve remote code execution (RCE) in build environments. Affected Components - Package: pnpm - Versions: All versions using @pnpm/config.env-replace and loadToken functionality - File: pnpm/network/auth-header/src/getAuthHeadersFromConfig.ts - loadToken() function - File: pnpm/config/config/src/readLocalConfig.ts - .npmrc environment variable substitution Technical Details Vulnerability Chain 1. Environment Variable Substitution - .npmrc supports ${VAR} syntax - Substitution occurs in readLocalConfig() 2. loadToken Execution - Uses spawnSync(helperPath, { shell: true }) - Only validates absolute path existence 3. Attack Flow Code Evidence pnpm/config/config/src/readLocalConfig.ts:17-18 pnpm/network/auth-header/src/getAuthHeadersFromConfig.ts:60-71…

# Patch Next advisory brief: CVE-2025-69262

Advisory: pnpm vulnerable to Command Injection via environment variable substitution
IDs: CVE-2025-69262, GHSA-2phv-j68v-wwqx
Record: https://patchnext.com/advisories/cve-2025-69262 (revision 2, source checked 26 Oct 2026, 12:41 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: pnpm 10.27.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm pnpm: affected >= 6.25.0, < 10.27.0; fixed in 10.27.0

## Suggested inspection (read-only)
- `npm ls pnpm --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on pnpm.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://osv.dev/vulnerability/GHSA-2phv-j68v-wwqx (OSV record GHSA-2phv-j68v-wwqx lists affected ranges: npm pnpm >=6.25.0 <10.27.0 (fixed))
- Verified: https://github.com/advisories/GHSA-2phv-j68v-wwqx (GitHub-reviewed advisory GHSA-2phv-j68v-wwqx lists affected ranges: npm pnpm >=6.25.0 <10.27.0)
