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 before 5.21.5 contains a cross-site request forgery vulnerability because the backend processes the safemode GET parameter in index.php without validating a CSRF token. Attackers can lure a logged-in administrator into opening a crafted link to disable global safe mode, writing safe_mode: false to config.yml, or enable session safe mode, disabling backend addons.
