Multiple XSS vulnerabilities in the Final Tiles Gallery plugin before 3.4.19 for WordPress allow remote attackers to inject arbitrary web script or HTML via the Title (aka imageTitle) or Caption (aka description) field of an image to wp-admin/admin-ajax.php.

The following themes for WordPress are vulnerable to Function Injections in versions up to and including Shapely <= 1.2.7, NewsMag <= 2.4.1, Activello <= 1.4.0, Illdy <= 2.1.4, Allegiant <= 1.2.2, Newspaper X <= 1.3.1, Pixova Lite <= 2.0.5, Brilliance <= 1.2.7, MedZone Lite <= 1.2.4, Regina Lite <= 2.0.4, Transcend <= 1.1.8, Affluent <= 1.1.0, Bonkers <= 1.0.4, Antreas <= 1.0.2, Sparkling <= 2.4.8, and NatureMag Lite <= 1.0.4. This is due to epsilon_framework_ajax_action. This makes it possible for unauthenticated attackers to call functions and achieve remote code execution.

The Brilliance <= 1.2.7, Activello <= 1.4.0, and Newspaper X <= 1.3.1 themes for WordPress are vulnerable to Plugin Activation/Deactivation. This is due to the 'activello_activate_plugin' and 'activello_deactivate_plugin' functions in the 'inc/welcome-screen/class-activello-welcome.php' file missing capability and security checks/nonces. This makes it possible for unauthenticated attackers to activate and deactivate arbitrary plugins installed on a vulnerable site.

A stored XSS vulnerability exists in the Modula Image Gallery plugin before 2.2.5 for WordPress. Successful exploitation of this vulnerability would allow an authenticated low-privileged user to inject arbitrary JavaScript code that is viewed by other users.

The Image Photo Gallery Final Tiles Grid WordPress plugin before 3.5.3 does not sanitise and escape the Description field when editing a gallery, allowing users with a role as low as contributor to perform Cross-Site Scripting attacks against other users having access to the gallery dashboard

The Strong Testimonials WordPress plugin before 3.0.3 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.

The CPO Companion WordPress plugin before 1.1.0 does not validate and escape some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as contributor to perform Stored Cross-Site Scripting attacks which could be used against high privilege users such as admins.

The CPO Companion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several of its content type settings parameters in versions up to, and including, 1.0.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Auth (subscriber+) Reflected Cross-Site Scripting (XSS) vulnerability in Macho Themes Regina Lite theme <= 2.0.7 versions.

Auth (subscriber+) Reflected Cross-Site Scripting (XSS) vulnerability in Macho Themes NewsMag theme <= 2.4.4 versions.

Cross-Site Request Forgery (CSRF) vulnerability in WPChill Strong Testimonials.This issue affects Strong Testimonials: from n/a through 3.1.10.

The Modula Image Gallery plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the zip upload functionality in all versions up to, and including, 2.11.10. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

The Modula Image Gallery plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's bundled FancyBox JavaScript library (versions <= 5.0.36) 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.
