The vulnerability resides in the \u003ccode\u003eshell.write\u003c/code\u003e function within the \u003ccode\u003esrc/index.ts\u003c/code\u003e file. By manipulating the \u003ccode\u003eDescription\u003c/code\u003e argument, a local attacker can inject arbitrary commands. Publicly disclosed exploits exist, increasing the risk of exploitation. The project maintainers have been notified but have not yet responded. This vulnerability poses a significant risk to systems where ssh-mcp is installed, potentially allowing attackers to execute commands with the privileges of the application.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker gains local access to a system with tufantunc ssh-mcp installed.\u003c/li\u003e\n\u003cli\u003eThe attacker identifies the vulnerable \u003ccode\u003eshell.write\u003c/code\u003e function in \u003ccode\u003esrc/index.ts\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious input containing shell commands embedded within the \u003ccode\u003eDescription\u003c/code\u003e argument.\u003c/li\u003e\n\u003cli\u003eThe attacker executes a function that calls \u003ccode\u003eshell.write\u003c/code\u003e with the crafted input.\u003c/li\u003e\n\u003cli\u003eThe \u003ccode\u003eshell.write\u003c/code\u003e function processes the malicious input without proper sanitization.\u003c/li\u003e\n\u003cli\u003eThe injected shell commands are executed by the system.\u003c/li\u003e\n\u003cli\u003eThe attacker gains unauthorized access to the system or its data.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-7039 allows a local attacker to execute arbitrary commands on the affected system.
