Doc Text:
A flaw was found in rsync. A local attacker with low privileges can exploit a symlink following vulnerability in the handling of input configuration files, such as those specified by `--files-from` or `--password-file`. This allows the attacker to read arbitrary files accessible to the rsync daemon process, leading to information disclosure.

Description OSIDB Bzimport 2026-08-13 15:51:45 UTC 
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.
