{"id":"CVE-2026-35356","aliases":["GHSA-gwm6-q8ch-hcfr"],"url":"https://o3.security/vulnerability/CVE-2026-35356","summary":"uutils coreutils install Arbitrary File Overwrite with -D via Path Component Symlink Race","details":"A Time-of-Check to Time-of-Use (TOCTOU) vulnerability exists in the install utility of uutils coreutils when using the -D flag. The command creates parent directories and subsequently performs a second path resolution to create the target file, neither of which is anchored to a directory file descriptor. An attacker with concurrent write access can replace a path component with a symbolic link between these operations, redirecting the privileged write to an arbitrary file system location.","published":"2026-04-22T16:08:17.812Z","modified":"2026-08-12T03:51:11.679637896Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"uu_install","fixedVersion":"0.7.0"}],"fix":{"url":"https://github.com/uutils/coreutils/pull/10140","label":"uutils/coreutils#10140"},"references":[{"type":"WEB","url":"https://github.com/uutils"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35356.json"},{"type":"ADVISORY","url":"https://github.com/uutils/coreutils/releases/tag/0.7.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35356"},{"type":"FIX","url":"https://github.com/uutils/coreutils/pull/10140"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:11.679637896Z"}}
