Alert meAnalysisAIv1 – Mar 12, 2026
RustDesk Client through version 1.4.5 on Windows, macOS, and Linux uses weak password hashing and improper object prototype handling in its password security and configuration encryption modules, allowing local authenticated attackers to extract embedded sensitive data including passwords and machine identifiers. The vulnerability affects critical cryptographic functions including symmetric_crypt() and decrypt_str_or_original(), enabling attackers with local access and valid credentials to compromise encrypted credentials and system identifiers. No patch is currently available.

This issue affects RustDesk Client: through 1.4.5.
Executive ViewAI
CVE-2026-30785 presents notable security risk rated CVSS 8.2. Successful exploitation could significantly impact the confidentiality, integrity, or availability of affected systems. Organizations should apply vendor updates when available and consider compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.
