GHSA-2FGQ-7J6H-9RM4
Vulnerability from github – Published: 2026-03-03 00:40 – Updated: 2026-03-30 13:19Summary
system.run allowed SHELLOPTS + PS4 environment injection to trigger command substitution during bash -lc xtrace expansion before the allowlisted command body executed.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected:
<= 2026.2.21-2(includes latest published npm version at triage time) - Patched (planned next release):
2026.2.22
Impact
In allowlist mode, an attacker who can invoke system.run with request-scoped env could execute additional shell commands outside the intended allowlisted command body.
Root Cause
Host exec env sanitization blocked startup-file vectors (BASH_ENV, ENV, etc.) but did not block SHELLOPTS/PS4. For shell wrappers (bash|sh|zsh ... -c/-lc), request env overrides were passed through and bash evaluated PS4 under xtrace, enabling command substitution.
Fix
- Block
SHELLOPTSandPS4in host exec env sanitizers (Node + macOS). - For shell wrappers (
bash|sh|zsh ... -c/-lc), reduce request-scoped env overrides to an explicit allowlist (TERM,LANG,LC_*,COLORTERM,NO_COLOR,FORCE_COLOR). - Add regression tests for TS and macOS paths.
Fix Commit(s)
e80c803fa887f9699ad87a9e906ab5c1ff85bd9a
Release Process Note
patched_versions is pre-set to the planned next release (2026.2.22). Once npm release 2026.2.22 is published, advisory publication is a final state action only.
Severity Rationale
This advisory is rated medium because exploitation requires a caller that can already invoke system.run with request-scoped env.
Under OpenClaw's documented trust model (SECURITY.md), authenticated Gateway callers are treated as trusted operators, and adversarial multi-operator / prompt-injection scenarios are out of scope.
The bug remains a real allowlist-intent bypass, but it does not cross a separate trust boundary in the documented deployment assumptions.
OpenClaw thanks @tdjackey for reporting.

"details": "### Summary\n`system.run` allowed `SHELLOPTS` + `PS4` environment injection to trigger command substitution during `bash -lc` xtrace expansion before the allowlisted command body executed.\n\n### Affected Packages / Versions\n- Package: `openclaw` (npm)\n- Affected: `\u003c= 2026.2.21-2` (includes latest published npm version at triage time)\n- Patched (planned next release): `2026.2.22`\n\n### Impact\nIn `allowlist` mode, an attacker who can invoke `system.run` with request-scoped `env` could execute additional shell commands outside the intended allowlisted command body.\n\n### Root Cause\nHost exec env sanitization blocked startup-file vectors (`BASH_ENV`, `ENV`, etc.) but did not block `SHELLOPTS`/`PS4`. For shell wrappers (`bash|sh|zsh ... -c/-lc`), request env overrides were passed through and `bash` evaluated `PS4` under `xtrace`, enabling command substitution.\n\n### Fix\n- Block `SHELLOPTS` and `PS4` in host exec env sanitizers (Node + macOS).\n- For shell wrappers (`bash|sh|zsh ... -c/-lc`), reduce request-scoped env overrides to an explicit allowlist (`TERM`, `LANG`, `LC_*`, `COLORTERM`, `NO_COLOR`, `FORCE_COLOR`).\n- Add regression tests for TS and macOS paths.\n\n### Fix Commit(s)\n- `e80c803fa887f9699ad87a9e906ab5c1ff85bd9a`\n\n### Release Process Note\n`patched_versions` is pre-set to the planned next release (`2026.2.22`). Once npm release `2026.2.22` is published, advisory publication is a final state action only.\n\n### Severity Rationale\nThis advisory is rated **medium** because exploitation requires a caller that can already invoke `system.run` with request-scoped `env`.\n\nUnder OpenClaw\u0027s documented trust model (`SECURITY.md`), authenticated Gateway callers are treated as trusted operators, and adversarial multi-operator / prompt-injection scenarios are out of scope.\n\nThe bug remains a real allowlist-intent bypass, but it does not cross a separate trust boundary in the documented deployment assumptions.\n\nOpenClaw thanks @tdjackey for reporting.",

Mitigation MIT-46
Strategy: Separation of Privilege
- Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
- Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
Mitigation
Because setting manipulation covers a diverse set of functions, any attempt at illustrating it will inevitably be incomplete. Rather than searching for a tight-knit relationship between the functions addressed in the setting manipulation category, take a step back and consider the sorts of system values that an attacker should not be allowed to control.
Mitigation
In general, do not allow user-provided or otherwise untrusted data to control sensitive values. The leverage that an attacker gains by controlling these values is not always immediately obvious, but do not underestimate the creativity of the attacker.
CAPEC-13: Subverting Environment Variable Values
The adversary directly or indirectly modifies environment variables used by or controlling the target software. The adversary's goal is to cause the target software to deviate from its expected operation in a manner that benefits the adversary.
CAPEC-146: XML Schema Poisoning
An adversary corrupts or modifies the content of XML schema information passed between a client and server for the purpose of undermining the security of the target. XML Schemas provide the structure and content definitions for XML documents. Schema poisoning is the ability to manipulate a schema either by replacing or modifying it to compromise the programs that process documents that use this schema.
CAPEC-176: Configuration/Environment Manipulation
An attacker manipulates files or settings external to a target application which affect the behavior of that application. For example, many applications use external configuration files and libraries - modification of these entities or otherwise affecting the application's ability to use them would constitute a configuration/environment manipulation attack.
CAPEC-203: Manipulate Registry Information
An adversary exploits a weakness in authorization in order to modify content within a registry (e.g., Windows Registry, Mac plist, application registry). Editing registry information can permit the adversary to hide configuration information or remove indicators of compromise to cover up activity. Many applications utilize registries to store configuration and service information. As such, modification of registry information can affect individual services (affecting billing, authorization, or even allowing for identity spoofing) or the overall configuration of a targeted application. For example, both Java RMI and SOAP use registries to track available services. Changing registry values is sometimes a preliminary step towards completing another attack pattern, but given the long term usage of many registry values, manipulation of registry information could be its own end.
CAPEC-270: Modification of Registry Run Keys
An adversary adds a new entry to the "run keys" in the Windows registry so that an application of their choosing is executed when a user logs in. In this way, the adversary can get their executable to operate and run on the target system with the authorized user's level of permissions. This attack is a good way for an adversary to run persistent spyware on a user's machine, such as a keylogger.
CAPEC-271: Schema Poisoning
An adversary corrupts or modifies the content of a schema for the purpose of undermining the security of the target. Schemas provide the structure and content definitions for resources used by an application. By replacing or modifying a schema, the adversary can affect how the application handles or interprets a resource, often leading to possible denial of service, entering into an unexpected state, or recording incomplete data.
CAPEC-579: Replace Winlogon Helper DLL
Winlogon is a part of Windows that performs logon actions. In Windows systems prior to Windows Vista, a registry key can be modified that causes Winlogon to load a DLL on startup. Adversaries may take advantage of this feature to load adversarial code at startup.
CAPEC-69: Target Programs with Elevated Privileges
This attack targets programs running with elevated privileges. The adversary tries to leverage a vulnerability in the running program and get arbitrary code to execute with elevated privileges.
CAPEC-76: Manipulating Web Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
CAPEC-77: Manipulating User-Controlled Variables
This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An adversary can override variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the adversary can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.
