# OpenProject 4.0.12

OpenProject 4.0.12 contains a bug fix and a security fix.

The following bugs have been fixed:

  - In projects with a lot of members and/or custom fields creating a
    work package could lead to an internal error (500)
    ([\#21068](https://community.openproject.org/work_packages/21068)).
  - In addition, a security bug has been fixed which potentially enabled
    XSS attacks.

For further information on the release, please refer to the [Changelog
v.4.0.12](https://community.openproject.org/versions/756) or take a look
at [GitHub](https://github.com/opf/openproject/tree/v4.0.12).
