Title
Executable Resolution from Untrusted Project Directory in Kiro CLI on Windows
Summary
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.
