The Blog, Posts and Category Filter for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Post and Category Filter widget in all versions up to, and including, 1.0.3 due to insufficient input sanitization and output escaping on user supplied 'post_types' attribute. 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 Post Carousel Slider for Elementor plugin for WordPress is vulnerable to improper authorization due to a missing capability check on the process_wbelps_promo_form() function in all versions up to, and including, 1.6.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to trigger the plugin’s support‐form handler to send arbitrary emails to the site’s support address.
