Project: Drupal core [1]
Version: 8.8.x-dev8.7.x-dev
Date: 2019-December-18
Security risk: *Moderately critical* 12∕25
AC:None/A:None/CI:None/II:None/E:Theoretical/TD:All [2]
Vulnerability: Denial of Service

Description: 
A visit to install.php can cause cached data to become corrupted. This could
cause a site to be impaired until caches are rebuilt.

Solution: 
Install the latest version:

   * If you are using Drupal 8.7.x, upgrade to Drupal 8.7.11 [3].
   * If you are using Drupal 8.8.x, upgrade to Drupal 8.8.1 [4].

Versions of Drupal 8 prior to 8.7.x are end-of-life and do not receive
security coverage.

To mitigate this issue in any version of Drupal 8, you can also block access
to install.php if it's not required.
