In Progress ShareFile Storage Zones Controller v5.12.6 and below, processing of queue items can send acknowledgements to an unvalidated callback URL, this behavior together with a race condition allows the attacker to cause FileCopyService to consume attacker-controlled metadata and content. Exploitation requires control over copy queue work and a race condition.
