Description
REDAXO versions before 5.21.3 have a cross-site request forgery (CSRF) vulnerability in the structure/history plugin. This flaw allows attackers to trick logged-in backend users into sending unvalidated GET requests that can delete all article snapshots or revert articles to previous states. The vulnerability can cause loss of content history or unintended content rollback.
