This vulnerability resides within the \u003ccode\u003eexecute_command\u003c/code\u003e function of the \u003ccode\u003esrc/index.ts\u003c/code\u003e file, a component of the MCP Interface. Successful exploitation allows a remote attacker to inject and execute arbitrary operating system commands on the server. The vulnerability has been publicly disclosed, making it a high-risk issue for systems running the affected software. The vendor was notified through an issue report but has not yet responded, potentially increasing the window of opportunity for attackers. Defenders should prioritize patching or mitigating this vulnerability to prevent unauthorized command execution and potential system compromise.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAttacker identifies a vulnerable instance of Sunwood-ai-labs command-executor-mcp-server running version 0.1.0 or earlier.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious request targeting the \u003ccode\u003eexecute_command\u003c/code\u003e function within the MCP Interface.\u003c/li\u003e\n\u003cli\u003eThe malicious request includes an OS command injection payload.\u003c/li\u003e\n\u003cli\u003eThe \u003ccode\u003eexecute_command\u003c/code\u003e function in \u003ccode\u003esrc/index.ts\u003c/code\u003e fails to properly sanitize or neutralize the input, passing it directly to the operating system.\u003c/li\u003e\n\u003cli\u003eThe operating system executes the attacker-supplied command with the privileges of the server process.\u003c/li\u003e\n\u003cli\u003eThe attacker gains arbitrary code execution on the server.\u003c/li\u003e\n\u003cli\u003eThe attacker can then use this access to perform further actions such as escalating privileges, installing malware, or exfiltrating sensitive data.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of CVE-2026-7593 allows an attacker to execute arbitrary commands on the affected server. This could lead to complete system compromise, including data theft, service disruption, or the deployment of malicious software. Given the ease of exploitation and the public availability of exploit code, organizations using the vulnerable Sunwood-ai-labs command-executor-mcp-server are at significant risk. While the exact number of affected installations is unknown, the potential impact is severe due to the possibility of full remote control over the compromised server.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eApply any available patches or updates from Sunwood-ai-labs to address CVE-2026-7593.\u003c/li\u003e\n\u003cli\u003eImplement input validation and sanitization measures within the \u003ccode\u003eexecute_command\u003c/code\u003e function to prevent OS command injection.\u003c/li\u003e\n\u003cli\u003eDeploy the Sigma rule \u003ccode\u003eDetect Suspicious Command Execution via MCP Server\u003c/code\u003e to identify potential exploitation attempts (see below).\u003c/li\u003e\n\u003cli\u003eMonitor network traffic for suspicious requests targeting the MCP Interface, specifically those containing command injection payloads.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-05-01T21:16:17Z","date_published":"2026-05-01T21:16:17Z","id":"/briefs/2026-05-sunwood-command-injection/","summary":"CVE-2026-7593 is an OS command injection vulnerability in Sunwood-ai-labs command-executor-mcp-server up to version 0.1.0, allowing remote attackers to execute arbitrary commands via the execute_command function in src/index.ts.","title":"Sunwood-ai-labs command-executor-mcp-server OS Command Injection Vulnerability","url":"https://feed.craftedsignal.io/briefs/2026-05-sunwood-command-injection/"}],"language":"en","title":"CraftedSignal Threat Feed — Command-Executor-Mcp-Server","version":"https://jsonfeed.org/version/1.1"}
