{"id":"GHSA-rm36-94g8-835r","summary":"Race Condition in Grunt","details":"file.copy operations in GruntJS are vulnerable to a TOCTOU race condition leading to arbitrary file write in GitHub repository gruntjs/grunt prior to 1.5.3. 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.","aliases":["CVE-2022-1537"],"modified":"2026-07-17T21:13:44.171543202Z","published":"2022-05-11T00:01:37Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2022-05-25T19:30:09Z","nvd_published_at":"2022-05-10T14:15:00Z","cwe_ids":["CWE-367"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-1537"},{"type":"WEB","url":"https://github.com/gruntjs/grunt/commit/58016ffac5ed9338b63ecc2a63710f5027362bae"},{"type":"PACKAGE","url":"https://github.com/gruntjs/grunt"},{"type":"WEB","url":"https://huntr.dev/bounties/0179c3e5-bc02-4fc9-8491-a1a319b51b4d"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2023/04/msg00006.html"}],"affected":[{"package":{"name":"grunt","ecosystem":"npm","purl":"pkg:npm/grunt"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.5.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/05/GHSA-rm36-94g8-835r/GHSA-rm36-94g8-835r.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
