About Jetbrains Hub
CVE-2026-50242 affects Jetbrains Hub, a product from Jetbrains. Before acting, confirm where Jetbrains Hub runs in your estate, who owns it and whether it is reachable from the internet, because exposure decides real risk more than the score alone.
What the flaw is
In plain terms: In JetBrains Hub before 2026.1.13757, 2025.3.148033, 2025.2.148048, 2025.1.148120, 2024.3.148430, 2024.2.148429 authentication bypass via direct database access leading to administrative access was possible
The weakness class is Missing Authentication. A critical function can be used without logging in.
Based on its CVSS vector, the flaw can be reached over the network, needs no login, and needs no user interaction. Apply the vendor fix and confirm exposure on internet facing and business critical assets first.
