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."}],"affected":[{"source":"security@ubuntu.com","affectedData":[{"vendor":"Uutils","product":"coreutils","defaultStatus":"unaffected","collectionURL":"https://github.com/uutils","packageName":"coreutils","platforms":["Linux","Unix","macOS"],"repo":"https://github.com/uutils/coreutils","versions":[{"version":"0","lessThan":"0.6.0","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security@ubuntu.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","baseScore":7.3,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.3,"impactScore":5.9}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-04-23T00:00:00+00:00","id":"CVE-2026-35338","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security@ubuntu.com","type":"Secondary","description":[{"lang":"en","value":"CWE-22"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*","versionEndExcluding":"0.6.0","matchCriteriaId":"87C33018-2E08-45B0-B69C-7FC224F7F883"}]}]}],"references":[{"url":"https://github.com/uutils/coreutils/pull/10033","source":"security@ubuntu.com","tags":["Issue Tracking","Patch"]},{"url":"https://github.com/uutils/coreutils/releases/tag/0.6.0","source":"security@ubuntu.com","tags":["Release Notes"]}]}
