Service interruption via unbounded deserialization depth
Published Sep 15, 2025 · Updated Nov 4, 2025
Deserialization in Apache Fory 0.5.0 through 0.12.1 allows remote authenticated users to interrupt service with deeply nested serialized data. The Java read paths increment recursion depth without enforcing a ceiling, so nested objects drive sustained CPU consumption until the host application becomes unresponsive. Reachability requires an application to accept attacker-controlled Fory data; the documented consequence is availability loss, not data access or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0.5.0 <=0.12.1
