Unauthenticated administrative actions via authentication bypass

Published Feb 9, 2026 · Updated Feb 9, 2026

Authentication bypass in JetBrains Hub before 2025.3.119807 allows remote attackers to perform administrative actions over the network. JetBrains has not disclosed the affected endpoint or the authentication check that accepts an unauthenticated request. No account or user interaction is required, and exploitation grants administrative access to Hub-managed identities and permissions without interrupting service.
