Prior to version 10.65.3, the HTTP MCP JSON-RPC endpoint at `/mcp` requires only OAuth `read` scope for all requests, then dispatches `tools/call` directly to handlers that include mutating tools. A read-only OAuth client can call `store_memory` and `delete_memory` through MCP even though the corresponding REST endpoints require `write` scope. Version 10.65.3 patches the issue."}], "lastModified": "2026-06-23T15:59:21.443", "sourceIdentifier": "security-advisories@github.com"}
