Upgrade REDAXO core to version 5.21.4 or later, where this missing authorization vulnerability has been fixed. No other mitigation is required as the vendor has provided an official fix.

Description

REDAXO core versions before 5.21.4 have a missing authorization vulnerability in the structure/version and structure/history frontend preview modes. These modes do not verify category or clang permissions for the previewed article, allowing any backend user or users with the history[article_rollback] permission to access unpublished, historic, or deleted content by manipulating parameters.
