The WP Recipe Maker plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 10.8.0. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to take ownership of any admin-authored recipe by rewriting its postauthor to the attacker's user ID, and unpublish it by overwriting its poststatus with the contributor's draft or pending post status. This requires the default 'recipeuseauthor' setting to be set to 'parent' for the ownership transfer to occur, though unpublishing remains possible regardless of this setting.

The WP Recipe Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Roundup Recipe Name field in all versions up to, and including, 9.8.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The WP Recipe Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘tooltip’ parameter in all versions up to, and including, 9.6.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The WP Recipe Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's [wprm-recipe-instructions] and [wprm-recipe-ingredients] shortcodes in all versions up to, and including, 9.1.0 due to insufficient restrictions on the 'grouptag' attribute . This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The WP Recipe Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wprm-recipe-roundup-item shortcode in all versions up to, and including, 9.3.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The WP Recipe Maker plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Video Embed parameter in all versions up to, and including, 9.2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with access to the recipe dashboard (which is administrator-only by default but can be assigned to arbitrary capabilities), to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The WP Recipe Maker plugin for WordPress is vulnerable to SQL Injection via the 'recipes' parameter in all versions up to, and including, 9.1.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
