{"id":"CVE-2026-24056","aliases":["GHSA-m733-5w8f-5ggw"],"url":"https://o3.security/vulnerability/CVE-2026-24056","summary":"pnpm has symlink traversal in file:/git dependencies","details":"pnpm is a package manager. Prior to version 10.28.2, when pnpm installs a `file:` (directory) or `git:` dependency, it follows symlinks and reads their target contents without constraining them to the package root. A malicious package containing a symlink to an absolute path (e.g., `/etc/passwd`, `~/.ssh/id_rsa`) causes pnpm to copy that file's contents into `node_modules`, leaking local data. The vulnerability only affects `file:` and `git:` dependencies. Registry packages (npm) have symlinks stripped during publish and are NOT affected. The issue impacts developers installing local/file dependencies andCI/CD pipelines installing git dependencies. It can lead to credential theft via symlinks to `~/.aws/credentials`, `~/.npmrc`, `~/.ssh/id_rsa`. Version 10.28.2 contains a patch.","published":"2026-01-26T21:59:32.287Z","modified":"2026-07-15T01:49:07.461167229Z","cvss":null,"epss":{"score":0.00469,"percentile":0.38144,"asOf":"2026-07-31"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"pnpm","fixedVersion":"10.28.2"}],"fix":{"url":"https://github.com/pnpm/pnpm/commit/b277b45bc35ae77ca72d7634d144bbd58a48b70f","label":"pnpm/pnpm@b277b45"},"references":[{"type":"WEB","url":"https://github.com/pnpm/pnpm/releases/tag/v10.28.2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/24xxx/CVE-2026-24056.json"},{"type":"ADVISORY","url":"https://github.com/pnpm/pnpm/security/advisories/GHSA-m733-5w8f-5ggw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-24056"},{"type":"FIX","url":"https://github.com/pnpm/pnpm/commit/b277b45bc35ae77ca72d7634d144bbd58a48b70f"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:07.461167229Z"}}
