CVE-2026-123292
LowCVSS 2.7Summary
In JetBrains Datalore before 2026.4, API tokens and sessions of removed or banned users remained valid. This means revoking a user's access did not invalidate their active session or token.
Risk Assessment
A removed or banned user may still access Datalore using a valid token or session, creating a risk of unauthorized access to data and resources.
Recommendation
Upgrade JetBrains Datalore to version 2026.4 or later. After upgrading, invalidate API tokens and sessions of removed and banned users.
