CVE-2025-61622

Deserialization of untrusted data inpython in pyforyversions 0.12.0 through 0.12.2, or thelegacypyfury versions from0.1.0 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 isvulnerable toremote 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.
