 https://cve.radiocsirt.org/vuln/ghsa-v2x6-wwfw-r2rq GHSA-v2x6-wwfw-r2rq — Agentgateway is missing parameter sanitization in MCP to OpenAPI conversion 2026-10-14T23:57:23.855770+00:00

Affected: Go: github.com/agentgateway/agentgateway

### Summary

When converting MCP `tools/call` request to OpenAPI request, input path, query, and header values are not sanitized.

### Details

When using the [MCP to OpenAPI](https://agentgateway.dev/docs/standalone/latest/mcp/connect/openapi/) feature, the proxy lacks proper sanitization of input parameters in the MCP call, allowing: * Injection of additional path or query parameters. * Injection of additional headers.

### Impacted Versions

This vulnerability is fixed in Agentgateway v0.12.0+. Users on older versions are recommended to upgrade to v0.12.0+.

This feature only impacts usage of the [MCP to OpenAPI](https://agentgateway.dev/docs/standalone/latest/mcp/connect/openapi/) feature
