Detailsinfo

A vulnerability classified as critical has been found in OpenClaw up to 2026.2.21. This affects an unknown code block of the component Environment Variable Handler. The manipulation of the argument HOME/ZDOTDIR with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

OpenClaw versions prior to 2026.2.22 fail to sanitize shell startup environment variables HOME and ZDOTDIR in the system.run function, allowing attackers to bypass command allowlist protections. Remote attackers can inject malicious startup files such as .bash_profile or .zshenv to achieve arbitrary code execution before allowlist-evaluated commands are executed.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-32056 since 03/10/2026. The exploitability is told to be difficult. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1202 for this issue.

Upgrading to version 2026.2.22 eliminates this vulnerability. Applying the patch c2c7114ed39a547ab6276e1e933029b9530ee906 is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
