CVE-2026-0830
Published: 09 January 2026
Summary
CVE-2026-0830 is a high-severity OS Command Injection (CWE-78) vulnerability in Amazon (inferred from references). Its CVSS base score is 8.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 33.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-0830 is an arbitrary command injection vulnerability (CWE-78) in the Kiro GitLab Merge-Request helper component of Kiro IDE versions before 0.6.18. The issue arises when the software processes specially crafted workspace folder names during the opening of maliciously crafted workspaces, enabling attackers to inject and execute arbitrary commands.
Exploitation requires local access (AV:L) with low attack complexity (AC:L), no privileges (PR:N), and user interaction (UI:R), such as convincing a user to open a malicious workspace. Successful attacks have no scope change (S:U) but result in high impacts on confidentiality, integrity, and availability (C:H/I:H/A:H), as reflected in the CVSS v3.1 base score of 7.8. This allows attackers to potentially execute commands with the privileges of the affected process.
Mitigation involves updating to the latest version of Kiro IDE. Official advisories, including the AWS security bulletin (https://aws.amazon.com/security/security-bulletins/2026-001-AWS/) and the Kiro changelog (https://kiro.dev/changelog/spec-correctness-and-cli/), emphasize this patch as the primary remediation step.

Mitigating Controls (NIST 800-53 r5) AI
Directly mitigates the command injection vulnerability by requiring timely patching of Kiro IDE to version 0.6.18 or later as specified in advisories.
Prevents arbitrary command execution by enforcing validation and sanitization of untrusted inputs like specially crafted workspace folder names.
Limits the impact of successful command injection by enforcing least privilege on the Kiro IDE process privileges.
