{"id":"GHSA-xf75-659h-cgg5","summary":"uutils coreutils has a Link Following Issue","details":"A vulnerability in the tail utility of uutils coreutils allows for the exfiltration of sensitive file contents when using the --follow=name option. Unlike GNU tail, the uutils implementation continues to monitor a path after it has been replaced by a symbolic link, subsequently outputting the contents of the link's target. In environments where a privileged user (e.g., root) monitors a log directory, a local attacker with write access to that directory can replace a log file with a symlink to a sensitive system file (such as /etc/shadow), causing tail to disclose the contents of the sensitive file.","aliases":["CVE-2026-35345"],"modified":"2026-09-10T03:50:44.903465205Z","published":"2026-04-22T18:31:44Z","database_specific":{"cwe_ids":["CWE-59"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-04-29T22:58:55Z","nvd_published_at":"2026-04-22T17:16:36Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35345"},{"type":"WEB","url":"https://github.com/uutils/coreutils/issues/10328"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"affected":[{"package":{"name":"coreutils","ecosystem":"crates.io","purl":"pkg:cargo/coreutils"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"0.8.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-xf75-659h-cgg5/GHSA-xf75-659h-cgg5.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:N"}]}
