pnpm 10.34

on Node.js NPM

Minor Changes

• Treat tarball-integrity mismatches against the lockfile as a hard failure by default. Previously, pnpm install (non-frozen) would log ERR_PNPM_TARBALL_INTEGRITY, silently re-resolve from the registry, and overwrite the locked integrity — which meant a compromised registry, proxy, or republished version could substitute attacker-controlled content on a clean machine even though the project shipped a committed lockfile.

  pnpm install now exits with ERR_PNPM_TARBALL_INTEGRITY and a hint pointing at the new opt-in flag.

  The only opt-in is pnpm install --update-checksums — narrowly scoped to refreshing the locked integrity values from what the registry currently serves. Mirrors yarn's flag of the same name. A warning still prints when the bypass takes effect so the operation is auditable.

  --force and pnpm update deliberately do not bypass the integrity check. They are routine refresh operations; silently overwriting a locked integrity in those flows would erase the protection a committed lockfile is supposed to provide. --frozen-lockfile behavior is unchanged. --fix-lockfile keeps its documented purpose (filling in missing lockfile entries) and is also not a bypass.

Patch Changes

• Pin unscoped per-registry settings (_authToken, _auth, username/_password, tokenHelper, inline cert/key) to the registry declared in the same config source at load time, so a later layer overriding registry= (workspace .npmrc, pnpm-workspace.yaml, CLI --registry) cannot redirect a credential or client certificate authored for a different host. A deprecation warning is emitted whenever an unscoped per-registry setting is encountered, naming the source and the URL it was pinned to. Reported by JUNYI LIU.
• Fixed minimumReleaseAge handling when cached metadata is abbreviated. The npm registry returns abbreviated package metadata (without the per-version time field) by default, which made the maturity check throw ERR_PNPM_MISSING_TIME whenever cached abbreviated metadata was reused. pnpm now upgrades cached abbreviated metadata to the full document via a follow-up fetch when minimumReleaseAge is active, persists the upgrade to the on-disk cache so subsequent installs skip the extra fetch, and lets ERR_PNPM_MISSING_TIME from the cache fast-path fall through to the network fetch even under strict mode.
• Reject git resolutions whose commit field is not a 40-character hexadecimal SHA before invoking git. A malicious lockfile could otherwise smuggle a value such as --upload-pack=<command> through git fetch / git checkout, which on SSH or local-file transports executes the supplied command.
• Reject patch files whose diff --git headers reference paths outside the patched package directory. Previously a malicious .patch file added via a pull request could write, delete, or rename arbitrary files reachable by the user running pnpm install.
• Fixed --prefix=<dir> not being honored when locating the workspace root. The --prefix → dir rename was applied after workspace detection, so workspace settings declared in <dir>/pnpm-workspace.yaml were not loaded when pnpm was invoked from outside <dir> #11535.
• Reject dependency aliases that contain path-traversal segments (such as @x/../../../../../.git/hooks) when reading them from a package manifest or symlinking them into node_modules. A malicious registry package could otherwise use a transitive dependency key to make pnpm install create symlinks at attacker-chosen paths outside the intended node_modules directory.
