Overview
CVE-2026-11931 is a medium-severity vulnerability. It was published on June 15, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical description
Incorrect default permissions in Kiro IDE on macOS and Linux before version 0.11.133 could expose the authentication token cache file to other local users or processes via world-readable permissions (0644) instead of owner-restricted permissions (0600).
To remediate this issue, users should upgrade to Kiro IDE version 0.11.133 or later. After upgrading and restarting the application, the cache file permissions are automatically updated on the next token refresh. Users operating in a multi-user environment can invalidate existing tokens by reauthenticating.
Remediation
Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
