CVE-2026-11931 - Insecure Permissions on Authentication Token Cache File in Kiro IDE

Summary

CVE-2026-11931 affects Kiro IDE on macOS and Linux before version 0.11.133. Incorrect default permissions leave the authentication token cache file world-readable (0644) instead of owner-restricted (0600), so other local users or processes could read it.

Mitigation

Fixed in 0.11.133. Update Kiro IDE to version 0.11.133 or later.
