Deserialization of Untrusted Data vulnerability in the Go implementation of Apache Fory allows an attacker to cause a denial of service by supplying crafted data containing malformed type metadata, which triggers an uncaught panic.

This issue affects Apache Fory: from 0.16.0 before 1.5.0.  Users of other language implementations are not affected.

Users are recommended to upgrade to version 1.5.0, which fixes the issue.
