1.6.1
CVE-2026-2256 describes a Command Injection vulnerability discovered in ModelScope's MS-Agent, a Python-based AI agent framework. This flaw allows an attacker to execute arbitrary operating system commands by manipulating the input prompts provided to the agent. The vulnerability impacts versions of MS-Agent up to and including v1.6.0rc1. A fix is expected in a future release.
The Command Injection vulnerability in MS-Agent poses a significant risk because it allows an attacker to gain complete control over the underlying system. By crafting malicious prompts, an attacker can inject and execute arbitrary OS commands, potentially leading to data breaches, system compromise, and denial of service. The blast radius extends to any data processed or stored by the MS-Agent, and successful exploitation could facilitate lateral movement within the network if the agent has sufficient privileges. This vulnerability shares similarities with other prompt injection attacks targeting AI models, where malicious input is used to bypass security controls and execute unintended actions.
CVE-2026-2256 was publicly disclosed on 2026-03-02. The EPSS score is currently pending evaluation. There are no known public proof-of-concept exploits available at this time. This vulnerability is not currently listed on the CISA KEV catalog.
Organizations deploying ModelScope MS-Agent in production environments, particularly those using it for sensitive tasks or processing confidential data, are at risk. Systems with limited input validation or inadequate security controls are especially vulnerable. Developers integrating MS-Agent into their applications should prioritize input sanitization.

Due to the lack of a specific patched version, immediate mitigation focuses on input validation and sanitization. Implement strict input validation routines to filter and sanitize all prompts received by the MS-Agent, preventing the injection of malicious commands. Consider using a Web Application Firewall (WAF) or proxy to inspect and block suspicious requests. Restrict the MS-Agent's access to sensitive resources and limit its privileges to the bare minimum required for its operation. Monitor system logs for unusual activity or command execution attempts. After a patched version is released, upgrade MS-Agent to the latest version immediately to eliminate the vulnerability.
Actualice el paquete ms-agent a una versión posterior a v1.6.0rc1. Esto solucionará la vulnerabilidad de inyección de comandos. Consulte la documentación de ModelScope para obtener instrucciones específicas sobre cómo actualizar el paquete.

CVE-2026-2256 is a Command Injection vulnerability affecting ModelScope MS-Agent versions up to v1.6.0rc1, allowing attackers to execute OS commands through crafted prompts.
You are affected if you are using ModelScope MS-Agent versions v1.6.0rc1 or earlier. Check your version and implement mitigations until a patch is available.
Upgrade to a patched version of MS-Agent as soon as it becomes available. Until then, implement strict input validation and sanitization to prevent command injection.
There are currently no confirmed reports of active exploitation, but the vulnerability is publicly known and should be mitigated proactively.
