What the vulnerability does

01Description

Improper trust boundary enforcement in Kiro IDE before version 0.8.0 on all supported platforms might allow a remote unauthenticated threat actor to execute arbitrary code via maliciously crafted project directory files that bypass workspace trust protections when a local user opens the directory. To remediate this issue, users should upgrade to version 0.8.0 or higher.
