CVE-2026-3598Public exploitNetwork attack vector

Sensitive configuration disclosure via reversible encoding

Published Mar 5, 2026 · Updated Mar 5, 2026

Weak cryptography in RustDesk Server Pro 1.7.5 and earlier allows remote attackers to recover sensitive data from exported configuration strings. The config export and generation routines apply Base64 encoding and reverse the resulting string instead of encrypting embedded values. Network access without authentication is sufficient to decode the export and read its embedded data, without reported integrity or availability impact.
