rsync < 3.5.0 Symlink Race Condition via --remove-source-files
CVE-2026-53800 is fixed in 4 products on 1 platform, first by SUSE-SU-2026:3657-1, released August 20, 2026. It is not reported as exploited. Patch Radar priority: Routine.
rsync before 3.5.0 contains a symlink race condition vulnerability in the --remove-source-files feature that allows attackers with symlink creation access to cause arbitrary file deletion. Attackers can atomically substitute a symlink for a source file between transfer completion and the unlink() call, causing rsync to delete the symlink target rather than the intended source file.
