Sensitive-data disclosure via reversible config encoding
Published Mar 5, 2026 · Updated Mar 5, 2026
Broken cryptography in RustDesk Client 1.4.5 and earlier allows remote attackers to recover secrets from imported configuration strings. The parseRustdeskUri() and importConfig() paths accept pseudo-encrypted configuration strings without cryptographic authenticity validation, leaving embedded data recoverable. Exposure requires access to a configuration string delivered through configuration import, a RustDesk URI, or the --config option; the reported consequence is disclosure only.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
