Summary
JetBrains Hub before 2026.2.52519 is affected. A missing critical step in authentication (CWE-304) allows two-factor authentication to be bypassed through the password reset flow. A remote attacker without privileges needs a user to interact with the flow and can gain high confidentiality and integrity impact.
