What is CVE-2025-54412?
CVE-2025-54412 is a high-severity code injection vulnerability in skops-dev skops, published on 26 Jul 2025. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
skops is a Python library which helps users share and ship their scikit-learn based models. Versions 0.11.0 and below contain a inconsistency in the OperatorFuncNode which can be exploited to hide the execution of untrusted operator methods. This can then be used in a code reuse attack to invoke seemingly safe functions and escalate to arbitrary code execution with minimal and misleading trusted types. This is fixed in version 0.12.0.
Weakness: CWE-351
