CVE-2025-61622

Description

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.
