A numeric truncation flaw was found in the RabbitMQ amqp091-go Go client library. The writeShortstr function in write.go casts the byte length of AMQP shortstr property values to uint8 without rejecting values longer than 255 bytes. An application that publishes AMQP messages with oversized CorrelationId, ReplyTo, MessageId, Expiration, UserId, AppId, ContentType, ContentEncoding, or Type fields silently serializes a wrapped length and a truncated prefix, reporting no error. The resulting metadata corruption can break request-reply correlation, routing, tracing, and downstream message processing.
