Executive Summary

CVE-2026-18980 is an approval-bypass vulnerability in the IronClaw software's built-in shell tool. It allows malicious commands to execute without user confirmation by exploiting how the tool classifies command risk. The vulnerability affects versions up to 0.29.1 and has been patched.

Detection Guidance

To detect this vulnerability, check if you are running IronClaw versions up to 0.29.1. Inspect the shell tool's command classification logic for improper handling of newline characters or sort commands with --compress-program flags. Review logs for unauthorized command executions or file modifications.

Impact Analysis

This vulnerability could allow attackers to execute arbitrary commands on your system, potentially leading to unauthorized file modification, deletion, or data exfiltration. It bypasses security checks when the shell tool is set to always_allow mode.

Compliance Impact

This vulnerability could lead to unauthorized command execution, potentially allowing access to or modification of sensitive data. For GDPR, this may result in unauthorized data processing or breaches, violating principles of data protection and user rights. For HIPAA, it could enable unauthorized access to protected health information, compromising confidentiality and integrity requirements.

Mitigation Strategies

Immediately update IronClaw to a patched version beyond 0.29.1. Disable the shell tool's AlwaysAllow mode if enabled. Implement stricter command risk classification to block newline-separated commands and sort-based payloads. Review and restrict symlink handling in file operations.
