WordPress before 4.9.9 and 5.x before 5.0.1 allows remote code execution because an _wp_attached_file Post Meta entry can be changed to an arbitrary string, such as one ending with a .jpg?file.php substring. An attacker with author privileges can execute arbitrary code by uploading a crafted image containing PHP code in the Exif metadata. Exploitation can leverage CVE-2019-8943.

The UltraEmbed – Advanced Iframe Plugin For WordPress with Gutenberg Block Included plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'iframe' shortcode in all versions up to, and including, 1.0.3 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 Visualizer: Tables and Charts Manager for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Import Data From File feature in all versions up to, and including, 3.11.8 due to insufficient input sanitization and output escaping on user supplied attributes.

The PressMart - Modern Elementor WooCommerce WordPress Theme theme for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 1.2.16.

The Brooklyn theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.9.9.2 via deserialization of untrusted input in the ot_decode function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

The CarSpot – Dealership Wordpress Classified Theme theme for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 2.4.3.
