What an attacker can do

A user could successfully send a message to an address or consume a message from a queue with a routing-type not supported by the corresponding address when that operation should actually be rejected on the basis that the user doesn't have permission to change the routing-type of the address. NVD’s CVSS 3.1 assessment (base score 4.3/10) rates confidentiality and availability impact as none; integrity impact as low. Source advisory’s CVSS 3.1 assessment (base score 4.3/10) rates confidentiality and availability impact as none; integrity impact as low.
