AI Analysis
Technical Summary
CVE-2026-4295 is a security vulnerability in Kiro IDE, an AI-powered integrated development environment for agentic software development. The flaw arises from improper trust boundary enforcement, which enables an attacker to execute arbitrary code by crafting a malicious project directory that, when opened by the user, triggers code execution. This affects all versions prior to 0.8.0. The vulnerability has been remediated in Kiro IDE version 0.8.0.
Potential Impact
Successful exploitation allows an attacker to execute arbitrary code on the user's system when a malicious project directory is opened in Kiro IDE versions before 0.8.0. This could lead to compromise of the user's environment running the IDE. There are no known exploits in the wild at this time.
Mitigation Recommendations
A fixed version, Kiro IDE 0.8.0, is available and should be applied to remediate this vulnerability. Users who cannot upgrade immediately should avoid opening project directories from untrusted sources to prevent exploitation.
