{"id":"CVE-2026-35338","summary":"uutils coreutils chmod Path Traversal Bypass of --preserve-root","details":"A vulnerability in the chmod utility of uutils coreutils allows users to bypass the --preserve-root safety mechanism. The implementation only validates if the target path is literally / and does not canonicalize the path. An attacker or accidental user can use path variants such as /../ or symbolic links to execute destructive recursive operations (e.g., chmod -R 000) on the entire root filesystem, leading to system-wide permission loss and potential complete system breakdown.","aliases":["GHSA-4c7q-4928-8445"],"modified":"2026-07-08T08:12:58.903686043Z","published":"2026-04-22T16:07:31.316Z","database_specific":{"cna_assigner":"canonical","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35338.json","cwe_ids":["CWE-22"]},"references":[{"type":"WEB","url":"https://github.com/uutils"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35338.json"},{"type":"ADVISORY","url":"https://github.com/uutils/coreutils/releases/tag/0.6.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35338"},{"type":"FIX","url":"https://github.com/uutils/coreutils/pull/10033"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/uutils/coreutils","events":[{"introduced":"0"},{"fixed":"2319a99057d11b0c9744c885df84806eea019166"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.6.0"}],"cpe":"cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*","source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"]}}],"versions":["latest-commit","0.5.0","0.4.0","0.3.0","0.2.2","0.2.0","0.1.0","0.0.30-delete","0.0.30","0.0.29","0.0.28","0.0.27","0.0.26","0.0.25","0.0.24","0.0.23","0.0.22","0.0.21","0.0.20","0.0.19","0.0.18","0.0.17","0.0.16","0.0.15","0.0.14","0.0.13","0.0.12","0.0.9","0.0.8","0.0.7","0.0.6","0.0.5","0.0.3","0.0.2","0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35338.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H"}]}
