Tool Execution Without Authorization via Piped Stdin in Kiro CLI

Missing input source validation in the tool authorization prompt in Kiro CLI before 1.28.0 allows a local attacker to execute arbitrary tools, including shell commands, without user approval by crafting content that is piped to kiro-cli via stdin.



We recommend you to upgrade to kiro-cli version 1.28.0 or later.
