Threats affecting pkg:npm/amazon/kiro-ide

Inclusion of functionality from an untrusted control sphere in the Kiro Powers feature in Amazon Kiro IDE before version 0.8.135 might allow remote unauthenticated actors to obtain sensitive information from a developer workstation. Crafted repository content can cause the agent to modify the workspace settings file, which redirects the Kiro Powers registry request to an actor controlled endpoint and sends workspace data to that endpoint when the Powers panel is opened. To remediate this issue, users should upgrade to Kiro IDE version 0.8.135 or later. Users who opened a project in an earlier version should also rotate any credentials that were present in that project.

Bulletin ID: 2026-074-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 08/04/2026 12:30 PM PDT Description: Kiro is an agentic IDE and command-line interface users install on their desktop. We identified CVE-2026-18656 and CVE-2026-18657, an issue where an uncontrolled search path element on Windows might allow an actor to execute arbitrary code via a maliciously crafted project directory containing a planted executable that is resolved before the system PATH when a local user opens the directory. Impacted versions: - Kiro IDE for Windows between versions 1.0.0 through 1.0.212 - Kiro CLI for Windows prior to v2.10.0 Please refer to the article below for the most up-to-date and complete information related to this AWS Security Bulletin.

CVE-2026-0830 is a high-severity OS command injection vulnerability in AWS Kiro IDE versions prior to 0.6.18. It arises from improper neutralization of special elements in workspace folder names processed by the Kiro GitLab Merge-Request helper. Opening a maliciously crafted workspace folder could allow an attacker to execute arbitrary OS commands. Users are advised to update to version 0.6.18 or later to mitigate this issue.
