CakePHP Queue is a queue-interop compatible queueing library. From 0.1.11 until 2.3.1, QueueManager::getUniqueId() generates identifiers for jobs with shouldBeUnique enabled from the job class, method, and parameters, but sorting parameter values drops associative-array keys. An unauthenticated attacker who can influence job parameters can submit semantically different data that produces the same identifier, resulting in legitimate jobs dropped as duplicate collisions. This issue is fixed in version 2.3.1.
