CVE-2021-24380Network attack vector

Administrator setting changes via forged requests

Published Aug 16, 2021 · Updated Aug 3, 2024

CSRF in Shantz WordPress QOTD 1.2.2 and earlier allows remote attackers to make logged-in administrators change plugin settings. The options page at wp-admin/options-general.php?page=shantz-wp-qotd.php accepts posted values without any CSRF check. A logged-in administrator must submit the forged request; the demonstrated consequence is arbitrary modification of plugin settings.
