{"id":"GHSA-wq63-vh5h-pr5p","summary":"uutils coreutils has a UNIX Symbolic Link (Symlink) Following issue","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":["CVE-2026-35372"],"modified":"2026-05-05T16:26:29.509542Z","published":"2026-04-22T18:31:46Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-04-30T17:53:37Z","nvd_published_at":"2026-04-22T17:16:41Z","cwe_ids":["CWE-61"],"severity":"MODERATE"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35372"},{"type":"WEB","url":"https://github.com/uutils/coreutils/pull/11253"},{"type":"WEB","url":"https://github.com/uutils/coreutils/commit/394c4b17f2f382b4be9f54389bcb79028de02f39"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"},{"type":"WEB","url":"https://github.com/uutils/coreutils/releases/tag/0.8.0"}],"affected":[{"package":{"name":"coreutils","ecosystem":"crates.io","purl":"pkg:cargo/coreutils"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.8.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-wq63-vh5h-pr5p/GHSA-wq63-vh5h-pr5p.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N"}]}
