CVE-2026-33010low · fixedCVSS 3.1
mcp-memory-service's Wildcard CORS with Credentials Enables Cross-Origin Memory Theft
### Summary When the HTTP server is enabled (`MCP_HTTP_ENABLED=true`), the application configures FastAPI's CORSMiddleware with `allow_origins=['*']`, `allow_credentials=True`, `allow_methods=["*"]`, and `allow_headers=["*"]`. The wildcard `Access-Control-Allow-Origin: *` header permits any website to read API responses cross-origin. When combined with anonymous access (`MCP_ALLOW_ANONYMOUS_ACCESS=true`) - the simplest way to get the HTTP dashboard working without OAuth - no credentials are need
CVE-2026-29787low · fixedCVSS 3.1
mcp-memory-service Vulnerable to System Information Disclosure via Health Endpoint
### Summary The `/api/health/detailed` endpoint returns detailed system information including OS version, Python version, CPU count, memory totals, disk usage, and the full database filesystem path. When `MCP_ALLOW_ANONYMOUS_ACCESS=true` is set (required for the HTTP server to function without OAuth/API key), this endpoint is accessible without authentication. Combined with the default `0.0.0.0` binding, this exposes sensitive reconnaissance data to the entire network. ### Details ### Vulnerabl
