- 3.3.3Simple BannerCVE List
A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.
Description
The Simple Banner WordPress plugin before 3.3.3 does not correctly limit the capabilities it grants to the user roles an administrator allows to manage its banners, granting such roles the full administrator capability, which allows users in a low-privileged role to escalate their privileges and fully compromise the site.
