What it is about
IntelliJ IDEA ist eine Java Entwicklungsumgebung (IDE). Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in JetBrains IntelliJ IDEA ausnutzen, um Informationen offenzulegen, um Code auszuführen und um Sicherheitsmaßnahmen zu umgehen.
Under what conditions?
Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.
What can happen in the worst case
An attacker could use the vulnerability to
- Informationen offenzulegen
- Code auszuführen
- Sicherheitsmaßnahmen zu umgehen
Am I affected?
Affected according to the BSI:
- JetBrains IntelliJ IDEA <2026.2
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- JetBrains IntelliJ IDEA 2026.2
Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
