{"id":"CVE-2026-35372","summary":"uutils coreutils ln Security Bypass via Improper Handling of the --no-dereference Flag","details":"A logic error in the ln utility of uutils coreutils allows the utility to dereference a symbolic link target even when the --no-dereference (or -n) flag is explicitly provided. The implementation previously only honored the \"no-dereference\" intent if the --force (overwrite) mode was also enabled. This flaw causes ln to follow a symbolic link that points to a directory and create new links inside that target directory instead of treating the symbolic link itself as the destination. In environments where a privileged user or system script uses ln -n to update a symlink, a local attacker could manipulate existing symbolic links to redirect file creation into sensitive directories, potentially leading to unauthorized file creation or system misconfiguration.","aliases":["GHSA-wq63-vh5h-pr5p"],"modified":"2026-07-08T08:12:58.214707503Z","published":"2026-04-22T16:08:58.696Z","database_specific":{"cna_assigner":"canonical","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35372.json","cwe_ids":["CWE-61"]},"references":[{"type":"WEB","url":"https://github.com/uutils"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35372.json"},{"type":"ADVISORY","url":"https://github.com/uutils/coreutils/releases/tag/0.8.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35372"},{"type":"FIX","url":"https://github.com/uutils/coreutils/pull/11253"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/uutils/coreutils","events":[{"introduced":"0"},{"fixed":"c4093734e2ebe2efb7d65e216cd1444664bcf26a"}],"database_specific":{"cpe":"cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.8.0"}],"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"]}}],"versions":["0.7.0","0.6.0","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-2026-35372.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:N/I:H/A:N"}]}
