What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

Description

REDAXO core before 5.21.5 contains a missing authorization vulnerability in the rex_api_package API function that lets non-admin backend users manage packages with only a valid CSRF token. Attackers holding a token, such as demoted admins with active sessions, can uninstall system addons like structure (dropping their database tables), deactivate, install, or activate packages, and delete non-system packages.
