Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Fory (fory-core, Maven) versions before 0.12.2 are vulnerable to a denial of service caused by insecure deserialization of untrusted data. A remote attacker can supply a large, specially crafted payload that consumes excessive CPU during deserialization, making the application unresponsive. Upgrade fory-core to version 0.12.2 or later.
