CVE-2026-89332Network attack vectorHinoki check available

Workspace data exfiltration via agent-written registry redirection

Published Sep 11, 2026 · Updated Sep 11, 2026

Inclusion of untrusted functionality in Kiro IDE before 0.8.135 allows remote attackers to exfiltrate sensitive workspace data. The Kiro agent accepts crafted repository content and writes a workspace setting that redirects the Powers registry to an attacker-controlled endpoint. Exfiltration occurs when a developer opens the crafted project and then opens the Powers panel, which sends workspace data to that endpoint.
