pnpm: Transitive dependency alias path traversal allows project path override via symlink replacement
GitHub lists this reviewed advisory for pnpm, pnpm. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
8.8 high
GitHub source severity; exploitability and local consequence require separate evidence.

02 / Applicability
The affected context
Affected versions, configuration prerequisites and known exclusions are public. Confirm each one against the deployed service.
pnpm
source listed< 10.34.0
## Summary pnpm allows a transitive dependency alias from registry package metadata to contain path traversal segments. During install, pnpm later uses that alias as a filesystem path when linking dependency nodes. As a result, a registry package can cause `pnpm install - ignore-scripts` to replace paths in the current project with symlinks to attacker-controlled dependency package directories. `.git/hooks` is only one useful target. The same primitive can replace other project-local paths that are consumed by later tools, for example: - `.husky` or `.githooks` for Git hook dispatchers - `scripts/`, `tools/`, `bin/`, or `tests/` for project scripts and CI commands - `.github/actions/` for local GitHub Actions used later in the workflow - `dist/` or other publish/build output directories before `pnpm pack` or `pnpm publish` - `node_modules/.bin` or undeclared `node_modules/` paths used by later command or module resolution Targets that are regular files can also be replaced with symlinks to a package directory, but those cases are usually denial of service. Directory targets are more useful because many developer tools execute or load files from those directories

03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
