Current Description

In Drupal Core versions 7.x prior to 7.62, 8.6.x prior to 8.6.6 and 8.5.x prior to 8.5.9; A remote code execution vulnerability exists in PHP's built-in phar stream wrapper when performing file operations on an untrusted phar:// URI.

This vulnerability is mitigated by the fact that such code paths typically require access to an administrative permission or an atypical configuration.
