CRITICAL CVSS 3.1
CVE-2026-30304
AI Code Command Injection Vulnerability
Description

In its design for automatic terminal command execution, AI Code offers two options: Execute safe commands and execute all commands. The description for the former states that commands determined by the model to be safe will be automatically executed, whereas if the model judges a command to be potentially destructive, it still requires user approval. However, this design is highly susceptible to prompt injection attacks. An attacker can employ a generic template to wrap any malicious command and mislead the model into misclassifying it as a 'safe' command, thereby bypassing the user approval requirement and resulting in arbitrary command execution.

CVSS 3.1 CRITICAL 134c704f-9b21-4f2e-91b3-4a467353bcc0
Solution
Prevent prompt injection by validating all commands before execution.
  • Only execute commands confirmed safe by the model.
  • Require user approval for all commands.
  • Implement strict input validation for commands.
  • Update AI model to detect malicious prompts.
