CVE-2026-102874 in AnyTool
Summary
by MITRE • 09/30/2026
A vulnerability was identified in HKUDS AnyTool 0.1.0. Affected is the function subprocess.run of the file anytool/local_server/main.py of the component Execute Endpoint. The manipulation of the argument command/shell leads to os command injection. It is possible to initiate the attack remotely. The exploit is publicly available and might be used. The project was informed of the problem early through an issue report but has not responded yet.

The vulnerability identified in HKUDS AnyTool version 0.1.0 represents a critical security flaw within its local server component, specifically located in the Execute Endpoint functionality found in the file anytool/local_server/main.py. This defect centers on the improper handling of arguments passed to the subprocess.run function, which serves as the mechanism for executing external commands or scripts. The core technical issue is an OS command injection vulnerability arising from the manipulation of the command and shell parameters provided by the user input. When the application constructs system calls based on these inputs without adequate sanitization or validation, it allows attackers to inject arbitrary operating system commands that are executed with the privileges of the running process. This type of flaw typically occurs when developer code concatenates unsanitized user-supplied data directly into a command string rather than using safe APIs that treat input as arguments rather than executable code.
From an operational perspective, this vulnerability poses a severe risk to the integrity and confidentiality of systems where HKUDS AnyTool is deployed. Because the exploit can be initiated remotely, an attacker does not need physical or local access to the target machine to compromise it. The availability of public exploits significantly lowers the barrier for entry, enabling even less skilled threat actors to leverage this flaw against vulnerable instances. Successful exploitation could lead to a complete takeover of the affected system, allowing the execution of arbitrary code, data exfiltration, lateral movement within a network, or the establishment of persistent backdoors. The fact that the project maintainers have been notified via an issue report but have not yet responded exacerbates the risk, as users are left without official patches or guidance on how to mitigate the exposure in production environments.
This vulnerability aligns with CWE-78, which defines Improper Neutralization of Special Elements used in an OS Command commonly known as OS Command Injection. It also maps directly to MITRE ATT&CK technique T1059, specifically sub-technique 004 for Command and Scripting Interpreter: Unix Shell Commands. The remote nature of the attack vector suggests it may be categorized under initial access or execution phases depending on how the local server is exposed to external networks. Organizations relying on this tool must treat it as compromised until a verified patch is released. Immediate mitigation strategies should include isolating any instances of HKUDS AnyTool behind strict firewall rules that prevent unauthorized remote access, disabling the Execute Endpoint if not strictly required for business operations, and monitoring system logs for unusual subprocess activity or command execution patterns indicative of injection attempts. Until an official fix is available, administrators should consider alternative tools with a stronger security track record to ensure operational continuity without exposing critical infrastructure to known exploitation vectors.
