Short explanation
The CVE-2026-89116 vulnerability in SAP yeoman-ui allows an attacker to execute arbitrary OS commands with developer privileges by manipulating the ApplicationWizard.installationLocation configuration [S0, S1].
This security flaw can be exploited via a manipulated settings.json file within a developer workspace [S0]. The patch status remains unconfirmed in official sources [S0].
What should be done?
- Follow official vendor advisories and security bulletins [S0].
- Exercise caution when opening untrusted workspace repositories [S0].
Chain of evidence and sources
SAP yeoman-ui bileşenindeki CVE-2026-89116 zafiyeti, child_process.execSync fonksiyonunun uygunsuz girdi doğrulamasından kaynaklanır [S0, S1].
Saldırganlar, ApplicationWizard.installationLocation değerini manipüle ederek geliştirici yetkileriyle komut çalıştırabilir [S0].
Show the technical text from the sources
The affected code used child_process.execSync with a shell string for generator installation and uninstallation. This allowed an attacker to execute arbitrary OS commands with the developer's privileges by manipulating the ApplicationWizard.installationLocation VS Code workspace configuration value. Because the value was passed directly to the shell without sanitisation, a malicious workspace repository could craft a settings.json that injects OS commands when a developer opens the project and triggers a generator installation.
