An uncontrolled search path element in Kiro IDE before version 1.0.228 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 opens the directory. To remediate this issue, users should upgrade to version 1.0.228 or higher.
