Upgrade REDAXO core to version 5.21.2 or later, where this vulnerability is fixed. No other mitigation is indicated or necessary as the fix addresses the root cause by validating sortable columns properly.
Description
CVE-2026-62998 is a medium severity vulnerability in the REDAXO PHP-based content management system core. Prior to version 5.21.2, the function rex_list::getSortColumn() improperly accepts a sort request parameter without verifying if the requested column is registered as sortable. This allows an authenticated backend user to cause the system to order query results by unauthorized columns, potentially exposing sensitive information such as user passwords through error-based enumeration. The issue is fixed in REDAXO version 5.21.2.
