What it is about
Xcode ist eine integrierte Entwicklungsumgebung von Apple, mit der man Programme für Mac OS X und iOS schreiben kann. Das Programm ist nur für Mac OS X verfügbar. Ein entfernter, anonymer oder lokaler Angreifer kann mehrere Schwachstellen in Apple Xcode ausnutzen, um Informationen offenzulegen und um einen Denial of Service Zustand herbeizuführen.
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
- einen Denial of Service Zustand herbeizuführen
Am I affected?
Affected according to the BSI:
- Apple Xcode <26.4
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Apple Xcode 26.4
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.
