## Description

The SEOPress plugin for WordPress is vulnerable to Sensitive Information Exposure via the %%_cf_<key>%% and %%_ucf_<key>%% dynamic variables in all versions up to, and including, 10.3, due to the plugin resolving any post, term or user meta key, including protected and credential-like keys, and printing the value into the page title, meta description and social meta tags. This makes it possible for authenticated attackers, with Editor-level access and above, to expose protected metadata of other users, such as an administrator's user meta, by adding these variables to the SEO metadata of content those users wrote.
