GHSA-m87h-jxr6-f82w
Concrete CMS allows unauthorized access because directories can be created with insecure permissions
Quick fix
GHSA-m87h-jxr6-f82w — concrete5/concrete5: upgrade to the fixed version with the command below.
composer require concrete5/concrete5:^8.5.13Details
Concrete CMS before 8.5.13 and 9.x before 9.2.2 allows unauthorized access because directories can be created with insecure permissions. File creation functions (such as the Mkdir() function) gives universal access (0777) to created folders by default. Excessive permissions can be granted when creating a directory with permissions greater than 0755 or when the permissions argument is not specified.
