CVE-2025-59328: Apache Fory: Denial of Service (DoS) due to Deserialization of Untrusted malicious large Data

[Chaokun Yang <chaokunyang () apache org>]

Severity: moderate 

Affected versions:

- Apache Fory (org.apache.fory:fory-core) 0.5.0 before 0.12.1

Description:

A vulnerability in Apache Fory allows a remote attacker to cause a Denial of Service (DoS). The issue stems from the 
insecure deserialization of untrusted data. An attacker can supply a large, specially crafted data payload that, when 
processed, consumes an excessive amount of CPU resources during the deserialization process. This leads to CPU 
exhaustion, rendering the application or system using the Apache Fory library unresponsive and unavailable to 
legitimate users.

Users of Apache Fory are strongly advised to upgrade to version 0.12.2 or later to mitigate this vulnerability. 
Developers of libraries and applications that depend on Apache Fory should update their dependency requirements to 
Apache Fory 0.12.2 or later and release new versions of their software.
