CVE-2026-53802
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk4th percentile - higher than 4% of all known CVEs
Summary
rsync before 3.5.0 contains an arbitrary file read vulnerability that allows attackers to read files accessible to the rsync daemon process by exploiting symlink following in input configuration file handling including --files-from, --password-file, and filter merge files. Attackers can place a symlink at a predictable --files-from or --password-file path, or supply a --files-from path that escapes the daemon module root, to read arbitrary files accessible to the rsync process.
Risk Assessment
The risk includes unauthorized access to sensitive files accessible to the rsync process, which could lead to data leakage.
Recommendation
It is recommended to upgrade rsync to version 3.5.0 or later and restrict access to configuration files and module directories.
