Attackers can trigger the vulnerability against a read-only rsync daemon module by providing a files-from entry containing both an interior and trailing backslash, causing the add_implied_include() function to under-count the trailing backslash when sizing the destination buffer.","published":"2026-08-13T15:20:00.117","modified":"2026-08-13T15:20:00.117","cvss":{"score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H"},"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-jhxm-j4mq-3fj4"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/rsync-heap-out-of-bounds-write-via-files-from-entry"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-13T15:20:00.117"}}
