Improper Privilege Management in Concrete CMS
Quick fix
GHSA-j4mv-2rv7-v2j9 — concrete5/core: upgrade to the fixed version with the command below.
composer require concrete5/core:^8.5.7Details
Privilege escalation from Editor to Admin using Groups in Concrete CMS versions 8.5.6 and below. If a group is granted "view" permissions on the bulkupdate page, then users in that group can escalate to being an administrator with a specially crafted curl. Fixed by adding a check for group permissions before allowing a group to be moved.
