CVE-2026-30304Network attack vector

Arbitrary command execution via prompt-injection misclassification

Published Mar 27, 2026 · Updated Mar 27, 2026

Prompt injection in AI Code 3.12.4 and earlier allows remote attackers to execute arbitrary terminal commands via a crafted prompt. The Tool Call Parser, Command Validation Logic, and Auto-Execution Module accept the model's safe classification for a wrapped malicious command and skip required approval. Exploitation requires user interaction and selection of Execute safe commands; successful commands execute in the local terminal context.
