Bug description:
  From https://simplesamlphp.org/security/202004-01:

  Date
  April 03, 2020
  Affected versions
  SimpleSAMLphp 1.18.5 and older
  Severity
  Low

  Background

  The module controller in SimpleSAML\Module that processes requests for pages hosted by modules, has code to identify paths ending with .php and process those as PHP code. If no other suitable way of handling the given path exists it presents the file to the browser.
  Description

  The check to identify paths ending with .php does not account for uppercase letters. If someone requests a path ending with e.g. .PHP and the server is serving the code from a case-insensitive file system, such as on Windows, the processing of the PHP code does not occur, and the source code is instead presented to the browser.
  Affected versions

  SimpleSAMLphp versions 1.18.5 and older.

  We will upgrade to version 1.18.7
