SCA: security update for pyfory (GHSA-538v-3wq9-4h3r)

critical Tenable Cloud Security Plugin ID 435494

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Deserialization of untrusted data in python in pyfory versions 0.12.0 through 0.12.2, or the legacy pyfury
 versions from 0.1.0 through 0.10.3: allows arbitrary code execution. An application is vulnerable if it
 reads pyfory serialized data from untrusted sources. An attacker can craft a data stream that selects
 pickle-fallback serializer during deserialization, leading to the execution of `pickle.loads`, which is
 vulnerable to remote code execution. Users are recommended to upgrade to pyfory version 0.12.3 or later,
 which has removed pickle fallback serializer and thus fixes this issue. (CVE-2025-61622)
