Publication Date: 11/10/2026 12:00 PM PST
Description:
Incorrect default file permissions in Kiro CLI before version 2.27.0 on macOS and Linux might allow other local users on the same host to read a user's session transcripts and prompt history, including any credentials or source code they contain. The CLI created its local session storage files with permissions that made them readable by all local users.
Impacted versions: Kiro CLI >= 1.16.0 AND < 2.27.0
