{"id":"CVE-2026-35372","aliases":["GHSA-wq63-vh5h-pr5p"],"url":"https://o3.security/vulnerability/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.","published":"2026-04-22T16:08:58.696Z","modified":"2026-08-05T03:32:04.535069143Z","cvss":{"score":5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"coreutils","fixedVersion":"0.8.0"}],"fix":{"url":"https://github.com/uutils/coreutils/pull/11253","label":"uutils/coreutils#11253"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-05T03:32:04.535069143Z"}}
