Received Received - Intake
Command Injection in OpenClaw exec Requests Bypassing Allowlist

Publication date: 2026-03-05

Last updated on: 2026-03-10

Assigner: VulnCheck

Description
OpenClaw versions prior to 2026.2.2 fail to properly validate Windows cmd.exe metacharacters in allowlist-gated exec requests (non-default configuration), allowing attackers to bypass command approval restrictions. Remote attackers can craft command strings with shell metacharacters like & or %...% to execute unapproved commands beyond the allowlisted operations.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability exists in OpenClaw versions prior to 2026.2.2, where the software fails to properly validate Windows cmd.exe metacharacters in allowlist-gated exec requests.

Because of this improper validation, attackers can bypass command approval restrictions by crafting command strings that include shell metacharacters such as & or %...%.

This allows remote attackers to execute commands that are not approved or intended by the allowlist, potentially leading to unauthorized actions.


How can this vulnerability impact me? :

The vulnerability can have a severe impact as it allows remote attackers to execute unapproved commands on the affected system.

This can lead to unauthorized system control, data compromise, or disruption of normal operations.

Given the high CVSS scores (9.2 in v4.0 and 9.8 in v3.1), the impact includes high confidentiality, integrity, and availability risks.


How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
