This vulnerability is capable of arbitrary file writes which can lead to local privilege escalation to the GruntJS user if a lower-privileged user has write access to both source and destination directories as the lower-privileged user can create a symlink to the GruntJS user's .bashrc file or replace /etc/shadow file if the GruntJS user is root.","published":"2022-05-10T00:00:00Z","modified":"2026-08-12T03:51:38.036617601Z","cvss":{"score":7.8,"severity":"HIGH","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":1,"affectedPackages":[{"ecosystem":"npm","name":"grunt","fixedVersion":"1.5.3"}],"fix":{"url":"https://github.com/gruntjs/grunt/commit/58016ffac5ed9338b63ecc2a63710f5027362bae","label":"gruntjs/grunt@58016ff"},"references":[{"type":"WEB","url":"https://huntr.dev/bounties/0179c3e5-bc02-4fc9-8491-a1a319b51b4d"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/1xxx/CVE-2022-1537.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-1537"},{"type":"FIX","url":"https://github.com/gruntjs/grunt/commit/58016ffac5ed9338b63ecc2a63710f5027362bae"},{"type":"ARTICLE","url":"https://lists.debian.org/debian-lts-announce/2023/04/msg00006.html"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:38.036617601Z"}}
