GHSA-8cw5-rv98-5c46
Summary Arbitrary PHP code execution in Drupal 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. Some Drupal code (core, contrib, and custom) may be performing file operations on insufficiently validated user input, thereby being exposed to this vulnerability. This vulnerability is mitigated by the fact that such code paths typically require access to an administrative permission or an atypical configuration.
