The vulnerability resides within the \u003ccode\u003efastmcp_server.py\u003c/code\u003e file of the \u003ccode\u003esave_file Tool\u003c/code\u003e component. It allows a remote attacker to perform path traversal by manipulating the \u003ccode\u003efilename/destination\u003c/code\u003e argument. The existence of a public exploit increases the risk of exploitation. The vendor has been notified but has not yet responded, leaving users vulnerable to potential attacks. This vulnerability poses a significant risk to systems utilizing the affected MLOps_MCP instance, potentially leading to unauthorized file access, modification, or even execution.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eThe attacker identifies an instance of MLOps_MCP version 1.0.0 accessible remotely.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious request targeting the \u003ccode\u003efastmcp_server.py\u003c/code\u003e file of the \u003ccode\u003esave_file Tool\u003c/code\u003e component.\u003c/li\u003e\n\u003cli\u003eWithin the request, the attacker manipulates the \u003ccode\u003efilename/destination\u003c/code\u003e argument to include a path traversal sequence (e.g., \u003ccode\u003e../../\u003c/code\u003e).\u003c/li\u003e\n\u003cli\u003eThe MLOps_MCP application processes the crafted request without proper validation of the supplied path.\u003c/li\u003e\n\u003cli\u003eThe application attempts to save the file to the attacker-specified path, traversing directories outside the intended storage location.\u003c/li\u003e\n\u003cli\u003eDepending on the server\u0026rsquo;s permissions, the attacker may be able to overwrite existing files or create new files in arbitrary locations.\u003c/li\u003e\n\u003cli\u003eIf the attacker overwrites a critical system file, it can lead to denial of service.\u003c/li\u003e\n\u003cli\u003eIf the attacker uploads and executes a malicious script, it can lead to complete system compromise.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this path traversal vulnerability (CVE-2026-7213) can lead to unauthorized file access, modification, or creation on the affected system.
