Real Estate Manager <= 7.3 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'before_price_text' Parameter

The Real Estate Manager – Property Listing and Agent Management plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'before_price_text' parameter in all versions up to, and including, 7.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The vulnerability is further enabled by the absence of any capability, nonce, or ownership check on the wp_ajax_rem_create_pro_ajax handler, and because the value is persisted via update_post_meta rather than post_content, the wp_kses filtering tied to the unfiltered_html capability does not apply.
