RabbitMQ amqp091-go: Connection Configuration Overwrite via Unsanitized TLS Path Parameter Injection

0th

RabbitMQ amqp091-go is a Go AMQP 0.9.1 client. Prior to 1.13.0, URI.String in uri.go concatenates CertFile, KeyFile, CACertFile, and ServerName values directly into an AMQPS query string instead of encoding them as URL query parameters with url.Values. If an application accepts a TLS asset path containing ampersand or equals delimiters and later reparses the serialized URI with ParseURI, the embedded delimiters can create or overwrite connection options, including paths to TLS certificate, key, or CA files. This can corrupt connection configuration or select unintended local cryptographic assets. This issue is fixed in version 1.13.0.
