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 5.21.3 contains a cross-site request forgery vulnerability in the structure/history plugin that allows attackers to delete history or roll back content via unvalidated GET requests. Attackers can lure logged-in backend users to a page triggering func=clearall or rex_history_function=snap, permanently deleting all article snapshots or reverting articles to earlier states.
