CVE-2026-70460
HighCVSS 8.1Exploitation Probability (EPSS)
Low risk37th percentile - higher than 37% of all known CVEs
Summary
rsync versions 2.3.3 before 3.5.0 contain a path traversal vulnerability that allows a malicious sender to escape the module root by exploiting symlinks within the module file tree when using --partial-dir or --backup-dir options. Attackers with write access to place a symlink under the module root, or who can exploit a pre-existing trusted symlink, can direct file writes to locations outside the intended module root, achieving arbitrary file write relative to the module root parent.
Risk Assessment
The vulnerability allows writing files outside the intended directory, potentially leading to system integrity compromise or unauthorized data modification.
Recommendation
Update rsync to version 3.5.0 or later, which contains the fix.
