When a privileged process archives an untrusted directory, the function follows symlinks without verifying that resolved targets remain within the source root, causing out-of-bounds files to be included in the archive as regular files and disclosed to the attacker.","published":"2026-08-10T18:18:50.610","modified":"2026-08-10T18:18:50.610","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://gist.github.com/thesmartshadow/e7dac0bb690ee17b9cc142154cb11726"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/tar-rs-symlink-escape-via-append-dir-all"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-10T18:18:50.610"}}
