CyberRota Analysis

AI-Generated

Versions of CodeWhale from 0.8.41 to 0.8.64 are vulnerable to remote code execution due to improper handling of approval requirements in the rlm_eval tool, allowing attackers to execute arbitrary Python code on the user's machine without approval or audit. This vulnerability poses a significant risk, as it can be exploited through prompt injection from untrusted content, leading to potential system compromise. Organizations using affected versions should prioritize upgrading to version 0.8.64 or later to mitigate this critical security risk.

Original NVD Description

CodeWhale (packages codewhale / codewhale-tui) versions >= 0.8.41 and < 0.8.64 contain a remote code execution vulnerability in the rlm_eval tool. The tool's approval_requirement() returns ApprovalRequirement::Auto, which the engine treats as 'never prompt,' causing arbitrary model-supplied Python code to run in a python3 interpreter without consulting the user's configured --approval-policy and without any approval prompt or audit step. An attacker can induce the agent to execute arbitrary code via prompt injection in untrusted content the agent reads (a web page, fetched URL, repository file, or MCP tool result); the companion rlm_open tool can stage such content. Code runs on the user's machine at the user's privilege level. Fixed in 0.8.64.
