Overview<\/strong><\/p>\n

In the ever-evolving landscape of cybersecurity, a new vulnerability has been discovered that could potentially put systems and data at risk. This vulnerability, designated as CVE-2025-6514, is associated with the mcp-remote software, which is used for connecting to MCP servers. The vulnerability arises due to the exposure of mcp-remote to OS command<\/a> injection when connecting to untrusted MCP servers, leading to a potential system compromise or data leakage. This issue is especially crucial due<\/a> to the high severity score of 9.6 assigned to it, indicating its potential for widespread damage if exploited.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-6514
\nSeverity: Critical (9.6 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: System compromise and data<\/a> leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

mcp-remote | All versions prior<\/a> to the patched<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability arises from the crafted input<\/a> from the authorization_endpoint response URL. If the mcp-remote software is connected to an untrusted MCP server, an attacker can inject commands<\/a> into the authorization_endpoint response URL. Because the software does not properly sanitize the input from this URL, the injected commands<\/a> are executed on the operating system running the mcp-remote software. This can lead to unauthorized<\/a> access, system compromise, and potential data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example of how the vulnerability might be exploited:<\/p>\n

POST \/authorization_endpoint HTTP\/1.1\nHost: untrusted.example.com\nContent-Type: application\/json\n{ \"malicious_payload\": \"injectable_os_command\" }<\/code><\/pre>\n
In the above example, the “injectable_os_command” is a stand-in for any command that can be executed on the operating system<\/a> running mcp-remote. Once this request is sent to the software, it executes the command, leading to the potential<\/a> consequences described earlier.<\/p>\n
Mitigation and Prevention<\/strong><\/p>\n
To mitigate this vulnerability, users of mcp-remote should immediately apply the vendor patch once available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary protection by identifying and blocking suspicious activities. Regularly updating and patching your software, using trusted servers<\/a>, and routinely monitoring system activities are also recommended preventative measures to enhance cybersecurity resilience.<\/p>\n","protected":false},"excerpt":{"rendered":"
