CVE-2026-10591: Amazon Kiro IDE

High severity, CVSS 8.8. EPSS: 0.7% chance of exploitation in the next 30 days.

Insufficient access control restrictions in the file write tool in Amazon Kiro IDE before version 0.11 might allow remote unauthenticated actors to execute arbitrary commands via crafted instructions that cause writes to execution-sensitive paths (such as .vscode/tasks.json), enabling auto-execution on folder open. To remediate this issue, users should upgrade to Kiro IDE version 0.11 or later.

Affected products

• Amazon Kiro IDE: before 0.11 (fixed in 0.11)
