The Spacer plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the motech_spacer_callback() function in all versions up to, and including, 3.0.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to view limited setting information.

The Hide My Site plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.2 due to the plugin not restricting access to the REST API when password protection is enabled. This makes it possible for unauthenticated attackers to gain unauthorized access to the site.

The Spacer WordPress plugin before 3.0.7 does not sanitize and escapes some of its settings, which could allow high-privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example, in multisite setup).
