System requirements

You can learn about the system components (like OS and database) needed for running Koha on the community wiki.

Security bugs

  • 39184 Server-side template injection leading to remote code execution

Bugfixes

Staff interface

Other bugs fixed

  • 36867 ILS-DI AuthorizedIPs should deny explicitly except those listed

    This patch updates the ILS-DI authorized IPs preference to deny all IPs not listed in the preference.

    Previously if no text was entered the ILS-DI service was accessible by all IPs, now it requires explicitly defining the IPs that can access the service.

    Upgrading libraries using ILS-DI should check that they have the necessary IPs defined in the system preference.
