CVE-2022-46829Network attack vector

Tokenless client connection with host consent

Published Dec 8, 2022 · Updated Apr 23, 2025

Improper authentication in JetBrains Gateway before 2022.3 allows remote attackers to establish a client connection without a valid token. JetBrains discloses that the connection is accepted despite the invalid token but does not identify the validation routine or explain the faulty check. The host must consent to the connection, and the published record does not specify what data or actions become available afterward.
