Executive Summary

CVE-2026-75915 is a vulnerability in CodeWhale versions before 0.8.64 where the js_execution tool fails to remove sensitive environment variables from the parent process before running Node.js. This allows malicious JavaScript code to access process.env and leak secrets like API keys or cloud credentials to the model context.

Detection Guidance

Check CodeWhale version with npm list codewhale or cargo list --package codewhale-tui. If version is >= 0.8.41 and < 0.8.64, the system is vulnerable. Monitor logs for unexpected JavaScript execution or environment variable access attempts.

Impact Analysis

Attackers could exploit this to steal sensitive data such as API keys, cloud credentials, or authentication tokens. This could lead to unauthorized access to systems, data breaches, or further attacks using exposed credentials. The vulnerability is exploitable even in auto-approve mode without user interaction.

Compliance Impact

This vulnerability could lead to unauthorized exposure of personal or sensitive data, violating GDPR and HIPAA requirements for data protection. Organizations using affected versions may face compliance violations, legal penalties, and reputational damage due to data leaks.

Mitigation Strategies

Upgrade CodeWhale to version 0.8.64 or later using npm update codewhale or cargo update -p codewhale-tui. If upgrading is not possible, restrict access to the js_execution tool or disable it entirely until patched.
