Please report security vulnerabilities by opening a new GitHub security advisory.

You can also send an email to [email protected], which is an alias to a subset of the scikit-learn maintainers' team.

If the security vulnerability is accepted, a patch will be crafted privately in order to prepare a dedicated bugfix release as timely as possible (depending on the complexity of the fix).

In addition to the options above, you can also report security vulnerabilities to tidelift.
