Untrusted request routing and forged acknowledgements permit copy-workflow manipulation in Progress ShareFile Storage Zones Controller

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
