The Go Pricing - WordPress Responsive Pricing Tables plugin for WordPress is vulnerable to PHP Object Injection in versions up to, and including, 3.3.19 via deserialization of untrusted input from the 'go_pricing' shortcode 'data' parameter. This allows authenticated attackers, with subscriber-level permissions and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

The Go Pricing - WordPress Responsive Pricing Tables plugin for WordPress is vulnerable to Stored Cross-Site Scripting via shortcodes in versions up to, and including, 3.3.19 due to insufficient input sanitization and output escaping. This makes it possible for contributor-level attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Go Pricing - WordPress Responsive Pricing Tables plugin for WordPress is vulnerable to unauthorized arbitrary file uploads due to an improper capability check on the 'validate_upload' function in versions up to, and including, 3.3.19. This makes it possible for authenticated attackers with a role that the administrator previously granted access to the plugin to upload arbitrary files on the affected site's server which may make remote code execution possible.

The Go Pricing - WordPress Responsive Pricing Tables plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'process_postdata' function in versions up to, and including, 3.3.19. This makes it possible for authenticated attackers with a role that the administrator previously granted access to the plugin to modify access to the plugin when it should only be the administrator's privilege.
