This vulnerability resides within the GitSearchRequest function located in the \u003ccode\u003emcp_server.py\u003c/code\u003e file, specifically affecting the Git Search API component. Successful exploitation allows a remote attacker to inject and execute arbitrary commands on the underlying system. The vulnerability stems from insufficient sanitization of user-supplied input to the \u003ccode\u003erepo_url\u003c/code\u003e or \u003ccode\u003epattern\u003c/code\u003e arguments. Publicly available exploits exist, increasing the risk of active exploitation.

This payload leverages shell metacharacters (e.g., \u003ccode\u003e;\u003c/code\u003e, \u003ccode\u003e|\u003c/code\u003e, \u003ccode\u003e\u0026amp;\u0026amp;\u003c/code\u003e) to chain malicious commands.\u003c/li\u003e\n\u003cli\u003eThe MCP server receives the request and passes the unsanitized \u003ccode\u003erepo_url\u003c/code\u003e or \u003ccode\u003epattern\u003c/code\u003e value to the GitSearchRequest function in \u003ccode\u003emcp_server.py\u003c/code\u003e.\u003c/li\u003e\n\u003cli\u003eThe \u003ccode\u003eGitSearchRequest\u003c/code\u003e function executes the injected command via a system call, effectively bypassing intended functionality.\u003c/li\u003e\n\u003cli\u003eThe attacker gains arbitrary command execution on the server, potentially allowing them to read sensitive files, modify system configurations, or establish a reverse shell.\u003c/li\u003e\n\u003cli\u003eThe attacker uses the reverse shell to further explore the network and escalate privileges.\u003c/li\u003e\n\u003c/ol\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation of this command injection vulnerability allows a remote attacker to execute arbitrary commands on the affected system. This can lead to complete system compromise, including data theft, modification, or destruction. Given the nature of MCP, which likely manages configurations and monitors other systems, a successful attack could cascade to other parts of the infrastructure, potentially affecting numerous systems across the network.\u003c/p\u003e\n\u003ch2 id=\"recommendation\"\u003eRecommendation\u003c/h2\u003e\n\u003cul\u003e\n\u003cli\u003eApply input validation and sanitization to the \u003ccode\u003erepo_url\u003c/code\u003e and \u003ccode\u003epattern\u003c/code\u003e parameters within the \u003ccode\u003eGitSearchRequest\u003c/code\u003e function to prevent command injection.\u003c/li\u003e\n\u003cli\u003eDeploy the Sigma rule \u003ccode\u003eDetect MCP Git Search API Command Injection Attempt\u003c/code\u003e to detect exploitation attempts targeting CVE-2026-7211.\u003c/li\u003e\n\u003cli\u003eMonitor web server logs for suspicious requests containing shell metacharacters in the \u003ccode\u003erepo_url\u003c/code\u003e or \u003ccode\u003epattern\u003c/code\u003e parameters as outlined in the Sigma rule and overview sections.\u003c/li\u003e\n\u003cli\u003eConsider isolating or taking offline affected MCP instances until a patch is available to mitigate the risks associated with CVE-2026-7211.\u003c/li\u003e\n\u003c/ul\u003e\n","date_modified":"2026-04-28T01:16:02Z","date_published":"2026-04-28T01:16:02Z","id":"/briefs/2026-04-mcp-command-injection/","summary":"A command injection vulnerability (CVE-2026-7211) exists in the GitSearchRequest function of dvladimirov MCP up to version 0.1.0, allowing a remote attacker to execute arbitrary commands by manipulating the repo_url or pattern argument.","title":"dvladimirov MCP Git Search API Command Injection Vulnerability","url":"https://feed.craftedsignal.io/briefs/2026-04-mcp-command-injection/"}],"language":"en","title":"CraftedSignal Threat Feed — Dvladimirov","version":"https://jsonfeed.org/version/1.1"}
