What is CVE-2021-24294?
CVE-2021-24294 is a medium-severity cross-site scripting vulnerability in Michael Leithold DSGVO All in one for WP, published on 24 May 2021. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
The dsgvoaio_write_log AJAX action of the DSGVO All in one for WP WordPress plugin before 4.0 did not sanitise or escape some POST parameter submitted before outputting them in the Log page in the administrator dashboard (wp-admin/admin.php?page=dsgvoaiofree-show-log). This could allow unauthenticated attackers to gain unauthorised access by using an XSS payload to create a rogue administrator account, which will be trigged when an administrator will view the logs.
