The Survey Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘ays_sections[5][questions][8][title]’ parameter in all versions up to, and including, 5.1.3.3 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 Quiz Maker Business, Developer, and Agency plugins for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘content’ parameter in all versions up to, and including, 8.8.0 (Business), up to, and including, 21.8.0 (Developer), and up to, and including, 31.8.0 (Agency) due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The Quiz Maker Business, Developer, and Agency plugins for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 8.8.0 (Business), up to, and including, 21.8.0 (Developer), and up to, and including, 31.8.0 (Agency).

This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Quiz Maker Business, Developer, and Agency plugins for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'ays_save_google_credentials' function in all versions up to, and including, 8.8.0 (Business), up to, and including, 21.8.0 (Developer), and up to, and including, 31.8.0 (Agency). This makes it possible for unauthenticated attackers to modify the Google Sheets integration credentials within the plugin's settings. Because the 'client_id' parameter is not sanitized or escaped when used in output, this vulnerability could also be leveraged to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Poll Maker – Versus Polls, Anonymous Polls, Image Polls plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 5.5.4. This is due to missing or incorrect nonce validation on the duplicate_poll() function.

The Chartify – WordPress Chart Plugin plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.9.5 via the 'source' parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files.

The Poll Maker – Versus Polls, Anonymous Polls, Image Polls plugin for WordPress is vulnerable to time-based SQL Injection via the ‘orderby’ parameter in all versions up to, and including, 5.4.6 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
