Command Injection in Clawdbot Docker Execution via PATH Environment Variable

High
steipete published GHSA-mc68-q9jw-2h3v Jan 31, 2026

Package

npm clawdbot (npm)

Affected versions

<= 2026.1.24

Patched versions

v2026.1.29

Description

Summary

A command injection vulnerability existed in Clawdbot’s Docker sandbox execution mechanism due to unsafe handling of the PATH environment variable when constructing shell commands.

An authenticated user able to control environment variables could influence command execution within the container context.
This issue has been fixed and regression tests have been added to prevent reintroduction.

Impact

In environments where Docker sandbox mode was enabled, authenticated users capable of supplying environment variables could affect the behavior of commands executed inside the container.

This could lead to:

  1. Execution of unintended commands inside the container
  2. Access to the container filesystem and environment variables
  3. Exposure of sensitive data
  4. Increased risk in misconfigured or privileged container environments

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. Learn more on MITRE.
