Account takeover in JetBrains Hub via predictable restore codes

IdentifiersCVE-2026-56141CWE-330

JetBrains Hub contains an account takeover vulnerability caused by predictable restore codes. In affected versions, restore codes used in the account recovery or restoration workflow could be predicted, allowing an attacker to abuse that mechanism to take control of a user account. The issue affects JetBrains Hub versions before 2026.1.13757, 2025.3.148033, 2025.2.148048, 2025.1.148120, 2024.3.148430, and 2024.2.148429.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in full account takeover of targeted JetBrains Hub user accounts. Depending on the privileges of the compromised account, this may allow unauthorized access to identity data, administrative functions, connected services, and further actions performed as the victim user.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, reduce exposure of account recovery and restore workflows where feasible, monitor for suspicious account recovery activity, and rotate or invalidate existing restore codes if the product supports doing so. Definitive remediation is to upgrade to a fixed version.

Remediation

Patch, then assume compromise.

Upgrade JetBrains Hub to a fixed release. The vulnerability is fixed in JetBrains Hub 2026.1.13757, 2025.3.148033, 2025.2.148048, 2025.1.148120, 2024.3.148430, and 2024.2.148429 and later in the respective release lines.
