A flaw has been found in WilliamCloudQi matlab-mcp-server up to ab88f6b9bf5f36f725e8628029f7f6dd0d9913ca. The affected element is the function generate_matlab_code/execute_matlab_code of the file src/index.ts of the component MCP Interface. Executing a manipulation of the argument scriptPath can lead to path traversal. The attack can be executed remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.
Casky was already ahead
This CVE exploits attack patterns that Casky's 331matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.
CVE-2026-7272 is a path traversal vulnerability in the WilliamCloudQi matlab-mcp-server that allows attackers to manipulate the scriptPath argument in the generate_matlab_code and execute_matlab_code functions. By crafting malicious input with directory traversal sequences (such as ../), an attacker can escape the intended directory sandbox and access arbitrary files on the system. This vulnerability carries a CVSS score of 7.3 (high severity) and can be exploited remotely, making it particularly dangerous for organizations using this MCP server component in cloud or networked environments. Any system running an affected version of matlab-mcp-server up to commit ab88f6b9bf5f36f725e8628029f7f6dd0d9913ca is at risk of unauthorized file access and information disclosure.
Casky's Claude AI-powered platform maps this vulnerability to MITRE ATT&CK techniques T1083 (File and Directory Discovery) and T1005 (Data from Local System), which represent the attacker's post-exploitation goals. While Casky currently shows zero matching skills for this specific CVE, practitioners using the platform would detect attack patterns through behavioral analysis of unusual file access attempts outside expected MATLAB working directories, suspicious scriptPath parameters containing traversal sequences, and access to sensitive configuration or source files. Security teams should focus on monitoring MCP server logs for path manipulation indicators, implementing strict input validation on scriptPath arguments, and applying the latest patches to matlab-mcp-server to prevent this attack chain before the attacker reaches the discovery and data exfiltration phases.
