Technical details

A vulnerability classified as CWE-602 (Client-Side Enforcement of Server-Side Security) exists in JetBrains IntelliJ IDEA before version 2026.2. The flaw allows an unauthenticated remote attacker to modify settings during a Remote Development session. Because the CVSS vector indicates a scope change (S:C) and high impact across confidentiality, integrity, and availability, this suggests that the settings modification can be leveraged to gain broader control over the host or the development environment. The issue is resolved in version 2026.2.
