Vulnerability from github – Published: 2026-04-02 21:32 – Updated: 2026-04-02 21:32

Details

Unsanitized input during web page generation in the Kiro Agent webview in Kiro IDE before version 0.8.140 allows a remote unauthenticated threat actor to execute arbitrary code via a potentially damaging crafted color theme name when a local user opens the workspace. This issue requires the user to trust the workspace when prompted.

To remediate this issue, users should upgrade to version 0.8.140.
