Inputs such as an incomplete percent escape or a truncated multibyte sequence cause the underlying decoder to throw synchronously, and the exception escapes the middie normalize step and terminates the Node.js process. The bypass affects applications that call middie.run directly on the standalone engine API, "},"products":[{"@id":"cpe:2.3:a:\\@fastify\\/middie:\\@fastify\\/middie:*:*:*:*:*:*:*:*","identifiers":{"cpe23":"cpe:2.3:a:\\@fastify\\/middie:\\@fastify\\/middie:*:*:*:*:*:*:*:*"}}],"status":"affected","action_statement":"Update to a fixed version: 9.3.3.","timestamp":"2026-07-01T12:05:42.403Z"}]}
