GHSA-wcr3-gm9f-f87q · Severity: critical · Ecosystem: pip — Ludwig framework is vulnerable to insecure deserialization through its predict() method.
The Ludwig framework thru 0.10.4 is vulnerable to insecure deserialization (CWE-502) through its predict() method. When a user provides a dataset file path to the predict() method, the framework automatically determines the file format. If the file is a pickle (.pkl) file, it is loaded using pandas.read_pickle() without any validation or security restrictions. This allows the deserialization of arbitrary Python objects via the unsafe pickle module. A remote attacker can exploit this by providing a maliciously crafted pickle file, leading to arbitrary code execution on the system running the Ludwig prediction.
Conclusion & alert: CVE-2026-31237 is rated Moderate Risk (62.7/100): CVSS Critical severity, with medium exploitation likelihood (EPSS 0.51%). Mandatory action: Review affected assets and schedule remediation.
