9.8 · CRITICALOverview
CVE-2024-53866 is a critical-severity vulnerability affecting pnpm pnpm. It was published on December 10, 2024 and has a CVSS 3.1 base score of 9.8 (CRITICAL).
This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
The package manager pnpm prior to version 9.15.0 seems to mishandle overrides and global cache: Overrides from one workspace leak into npm metadata saved in global cache; npm metadata from global cache affects other workspaces; and installs by default don't revalidate the data (including on first lockfile generation). This can make workspace A (even running with `ignore-scripts=true`) posion global cache and execute scripts in workspace B. Users generally expect `ignore-scripts` to be sufficient to prevent immediate code execution on install (e.g. when the tree is just repacked/bundled without executing it). Here, that expectation is broken. Global state integrity is lost via operations that one would expect to be secure, enabling subsequently running arbitrary code execution on installs. Version 9.15.0 fixes the issue. As a work-around, use separate cache and store dirs in each workspace.
Remediation
Check the references section for vendor advisories and patches from pnpm. Update pnpm to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
