Attackers can exploit improper handling of the /./ notation or forge delta-basis transfers referencing xname paths that cross the /./ boundary to gain unauthorized read or write access to files outside the module's subtree.","published":"2026-08-13T15:19:43.690","modified":"2026-08-13T15:19:43.690","cvss":{"score":7.4,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/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-wj7w-vh23-mm44"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/rsync-path-confinement-bypass-via-boundary-marker-in-chroot-mode"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T15:19:43.690"}}
