HIGH 8.8UPGRADE

CVE-2026-50016 is a high-severity flaw (CVSS 8.8) affecting pnpm. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

pnpm is a package manager. Prior to 10.34.0 and 11.4.0, 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. This vu

pnpm pnpm UPGRADE

Affected: < 10.34.0 · >= 11.0.0 and < 11.4.0

Fixed in: 10.34.0, 11.4.0

Safe to downgrade to: a release before 11.0.0

1. Check installed version

npm ls pnpm

2. UPGRADE to 10.34.0

npm install pnpm@">=10.34.0"

3. If no update is available yet, DOWNGRADE to a release before 11.0.0

npm view pnpm versions npm install pnpm@"<11.0.0"

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
