    Apache Fory PyFory Deserialization of Untrusted Data

    CVE-2026-48207 · GHSA-m5gw-83w2-7749

    Affected
    • PyPI pyfory >= 0.13.0, < 1.0.0
    Fixed in
    1.0.0· Vendor fix available
    Issue
    Fory PyFory's ReduceSerializer could bypass documented DeserializationPolicy validation hooks during reduce-state restoration and global-name resolution. An application is vulnerable if it deserializes attacker-controlled data using PyFory Python-native mode with strict mode disabled and relies on DeserializationPolicy to restrict unsafe classes, functions, or module attributes. This issue affects Apache Fory: from before 1.0.0. Mitigation: Users of Apache Fory are recommended to upgrade to version 1.0.0 or later, which enforces DeserializationPolicy validation for the affected ReduceSerializer paths and thus fixes this issue.

    Recommended action: Upgrade to 1.0.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
