The daemon calls chdir() to the module root at session initialization without resolving symlinks via realpath() or equivalent, causing subsequent relative-path operations to reference files relative to the symlink target rather than the intended module root, enabling unauthorized file access.","published":"2026-08-13T15:19:42.190","modified":"2026-08-13T15:19:42.190","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/RsyncProject/rsync/releases/tag/v3.5.0"},{"type":"WEB","url":"https://github.com/RsyncProject/rsync/security/advisories/GHSA-ffg2-fr5g-3rxw"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/rsync-path-traversal-via-symlink-module-root"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T15:19:42.190"}}
