The Ultimate Classified Listings plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.5. This is due to missing or incorrect nonce validation on the update_profile function. This makes it possible for unauthenticated attackers to modify victim's email via a forged request, which might lead to account takeover, granted they can trick a user into performing an action such as clicking on a link.

The Ultimate Classified Listings plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Title parameter in all versions up to, and including, 1.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level access, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

The Ultimate Classified Listings WordPress plugin before 1.4 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

The Ultimate Classified Listings WordPress plugin before 1.3 does not sanitise and escape a parameter before outputting it back in the page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

The Ultimate Classified Listings WordPress plugin before 1.3 does not validate the `ucl_page` and `layout` parameters allowing unauthenticated users to access PHP files on the server from the listings page

The Product Expiry for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'save_settings' function in versions up to, and including, 2.5.

The Real Estate Manager plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 7.2 due to insufficient restriction on the 'rem_save_profile_front' function. This makes it possible for authenticated attackers, with minimal permissions such as a subscriber, to modify their user role by supplying the 'wp_capabilities' parameter during a profile update.
