CVE-2025-64681Network attack vector

User-limit bypass via invitation race

Published Nov 10, 2025 · Updated Nov 10, 2025

Authorization bypass in JetBrains Hub before 2025.3.104992 allows remote authenticated users to exceed the user limit through invitations. JetBrains has not disclosed which invitation-processing operation races or how concurrent requests evade the limit check. Administrative privileges are required, and the bounded consequence is unauthorized growth of the Hub user population rather than confidentiality or availability impact.
