What is CVE-2026-117534?

The Structure/History Plugin in REDAXO prior to version 5.21.3 is susceptible to a cross-site request forgery vulnerability. This flaw allows attackers to manipulate logged-in backend users into executing unvalidated GET requests, specifically targeting actions such as func=clearall or rex_history_function=snap. Consequently, this can result in the deletion of all article snapshots or the unintended reversion of articles to their previous states, jeopardizing content integrity and security.
