<!-- maintainer-action:start --> ## Maintainer Action Plan This report is ready to review with the shared patch branch. Start with the PR and the expected fixed behavior, then use the detailed exploit narrative below only if you want to replay the original path. - Advisory: `CAND-PNPM-122` / `GHSA-3qhv-2rgh-x77r` - Advisory URL: https://github.com/pnpm/pnpm/security/advisories/GHSA-3qhv-2rgh-x77r - Shared patch PR: https://github.com/pnpm/pnpm-ghsa-j2hc-m6cf-6jm8/pull/1 - Shared patch branch: `security/ghsa-batch-2026-06-09` - Patch commit: `a93449314f398cf4bdf2e28d033c02d37395ad22` - Base commit: `origin/main` `55a4035abf1ae3fe7208ba1f5ef43c5eff58ccec` - Maintainer priority: `start-here` - Component: `pnpm config/env replacement and registry auth` - Patch area: project .npmrc env placeholders are not expanded into registry/auth destinations - Affected packages: `npm:pnpm`, `npm:@pnpm/config.reader`, `rust:pacquet` - CWE IDs: `CWE-201`, `CWE-200`, `CWE-522` - Conservative CVSS: `6.5` / `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N` - Next action: review the shared patch branch for this component, set the final affected version range, merge and release the fix, then publish or close the advisory. ### Expected Patched Behavior Project `.npmrc` environment placeholders do not expand into registry or auth destinations; the secret is absent from the request URL and auth header. ### Files And Tests To Review - `config/reader/src/loadNpmrcFiles.ts` - `config/reader/src/getOptionsFromRootManifest.ts` - `config/reader/test/index.ts` - `config/reader/test/getOptionsFromRootManifest.test.ts` - `pacquet/crates/config/src/npmrc_auth.rs` - `pacquet/crates/config/src/npmrc_auth/tests.rs` - `pacquet/crates/config/src/workspace_yaml.rs` - `pacquet/crates/config/src/workspace_yaml/tests.rs` - `.changeset/sharp-registry-env-placeholders.md` ### Focused Validation Run these from a checkout of the shared patch branch.

A malicious repository could cause dependency resolution to send victim environment secrets to an attacker-selected registry before lifecycle scripts run. ### Details The vulnerable TypeScript pnpm path was: - `config/reader/src/loadNpmrcFiles.ts` loaded project `.npmrc` and substituted environment placeholders in keys and values. - `config/reader/src/getOptionsFromRootManifest.ts` substituted environment placeholders inside workspace `registry`, `regis
