Description
CVE-2026-10591 is a high-severity vulnerability in AWS Kiro IDE versions before 0.11. It involves incorrect permission assignment in the file write tool, allowing remote unauthenticated actors to execute arbitrary commands by writing to execution-sensitive paths such as .vscode/tasks.json. This can lead to automatic execution of malicious instructions when a folder is opened. The issue is fixed in version 0.11 and later.
