CVE-2026-53795: Samba Rsync

High severity, CVSS 8.1. EPSS: 0.4% chance of exploitation in the next 30 days.

rsync before 3.5.0 contains an arbitrary file write vulnerability that allows attackers to write files outside the intended destination tree by specifying an absolute path via --temp-dir or --link-dest options. The rename-confinement logic is bypassed when these options resolve to paths outside the destination tree, enabling attacker-controlled values to write files to arbitrary locations accessible to the rsync process.

Affected products

• Samba Rsync: before 3.5.0 (fixed in 3.5.0)
