CVE-2026-4295: Aws Kiro IDE

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

Improper trust boundary enforcement in Kiro IDE before version 0.8.0 on all supported platforms might allow a remote unauthenticated threat actor to execute arbitrary code via maliciously crafted project directory files that bypass workspace trust protections when a local user opens the directory. To remediate this issue, users should upgrade to version 0.8.0 or higher.

Affected products

• Aws Kiro IDE: from 0.1.0, before 0.8.0 (fixed in 0.8.0)
