CVE-2018-17831
In REDAXO before 5.6.3, a critical SQL injection vulnerability has been discovered in the rex_list class because of the prepareQuery function in core/lib/list.php, via the index.php?page=users/users sort parameter.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.05%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
