AI risk analysis

Summary: The flaw allows a remote unauthenticated actor to execute arbitrary code by manipulating the search path in Kiro CLI versions before 2.10.0 on Windows.
Exploitability: Exploitation requires control over a project directory and starting Kiro CLI within it; moderately hard due to workspace trust protections but can be bypassed with a maliciously crafted directory.
Blast radius: If exploited, the impact is high as it could lead to full code execution on affected systems, potentially leading to data loss or system compromise.
Prioritized remediation: Upgrade Kiro CLI to version 2.10.0 or higher immediately.

NVD description

An uncontrolled search path element in Kiro CLI before version 2.10.0 on Windows might allow a remote unauthenticated actor to execute arbitrary code via a maliciously crafted project directory containing an executable that bypasses workspace trust protections when a local user starts Kiro CLI in the directory. To remediate this issue, users should upgrade to version 2.10.0 or higher.
