github.com/docker/mcp-gateway fixed: 0.28.0 
Upgrade github.com/docker/mcp-gateway to 0.28.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/docker/mcp-gateway

How to Check if You Are Affected

To determine whether your application is affected by CVE-2025-64443, inspect your project dependencies for Github.com/docker/mcp gateway:

inspect dependencies for github.com/docker/mcp-gateway

Analyze the terminal output to locate any version of Github.com/docker/mcp gateway in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.28.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-749: Exposed Dangerous Method or Function, where the product provides an applications programming interface (api) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted. In Github.com/docker/mcp gateway, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact When ran in sse or streaming mode (--transport), the Docker MCP Gateway is vulnerable to a DNS rebinding attack. Vulnerability allows for Browser-Based exploitation of any MCP servers that are executing within the Docker MCP Gateway. Any tools or other features exposed by MCP servers can be manipulated by an attacker who is able to get a victim to visit a malicious website, or if a victim is served a malicious advertisement. The MCP Gateway is not prone to this attack when started in its default stdio mode, which does not listen on any network ports. ### Patches Patch available in version v0.28.0 ### Workarounds Do not start the MCP gateway in sse or streaming mode (use default stdio)
