The PDF Thumbnail Generator plugin for WordPress is vulnerable to Reflected Cross-Site Scripting due to the use of add_query_arg without appropriate escaping on the URL in all versions up to, and including, 1.3. 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 WP SVG Images plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘type’ parameter in all versions up to, and including, 4.3 due to insufficient input sanitization. This makes it possible for authenticated attackers, with Author-level access and above, who have permissions to upload sanitized files, to bypass SVG sanitization and inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. A bypass to the patch in version 4.3 was discovered and fixed completely in version 4.4.

Cross-Site Request Forgery (CSRF) vulnerability in KubiQ CPT base plugin <= 5.8 at WordPress allows an attacker to delete the CPT base.

The WP SVG images WordPress plugin before 3.4 did not sanitise the SVG files uploaded, which could allow low privilege users such as author+ to upload a malicious SVG and then perform XSS attacks by inducing another user to access the file directly. In v3.4, the plugin restricted such upload to editors and admin, with an option to also allow author to do so. The description of the plugin has also been updated with a security warning as upload of such content is intended.
