CWE-59
AllowedImproper Link Resolution Before File Access ('Link Following')
Abstraction: Base · Status: Draft
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
2244 vulnerabilities reference this CWE, most recent first.

GHSA-MWCG-WFQ3-4GJC
Vulnerability from github – Published: 2026-03-03 19:18 – Updated: 2026-03-30 13:34Summary
In openclaw@2026.2.24, approval-bound system.run on node hosts could be influenced by mutable symlink cwd targets between approval and execution.
Details
Approval matching on the gateway validated command/argv and binding fields, including cwd, as provided text. Node execution later used runtime cwd resolution. A symlinked cwd could therefore be retargeted after approval and before spawn.
OpenClaw's trust model does not treat one shared gateway as a multi-tenant adversarial boundary, but approval integrity is still a security boundary for operator-reviewed command execution.
Affected Packages / Versions
- Package:
openclaw(npm) - Affected:
<= 2026.2.24 - Patched:
>= 2026.2.25
Fix Commit(s)
f789f880c934caa8be25b38832f27f90f37903db
Remediation
The fix adds defense-in-depth hardening for approval-bound node execution:
- reject symlink cwd paths for approval-bound system.run
- canonicalize path-like executable argv before spawn
- bind CLI approval requests to exact commandArgv
Release Process Note
Patched version is pre-set to the release (2026.2.25). Advisory published with npm release 2026.2.25.
OpenClaw thanks @tdjackey for reporting.

Mitigation MIT-48.1
Strategy: Separation of Privilege
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
CAPEC-132: Symlink Attack
An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.
CAPEC-17: Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
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.
