The GutenBee – Gutenberg Blocks plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.20.1 via the gutenbee_file_and_ext_json function. This is due to a flawed strpos() substring check that only verifies whether the filename contains the string '.json' rather than confirming the filename ends with a .json extension, allowing double-extension filenames like shell.json.php to bypass validation. This makes it possible for authenticated attackers, with author-level access and above, to upload files that may be executable, which makes remote code execution possible.

The AudioIgniter plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 2.0.2. This is due to the handle_playlist_endpoint() function (hooked to template_redirect) accepting a user-controlled playlist ID via the audioigniter_playlist_id query var or the /audioigniter/playlist/{id}/ rewrite rule and returning playlist track data without performing any authentication, capability, or post_status check — only the post_type is validated. This makes it possible for unauthenticated attackers to view track metadata (titles, artists, audio URLs, buy links, download URLs, and cover images) of any playlist on the site, including those in draft, private, pending, or trash status.

The GutenBee – Gutenberg Blocks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via parameters in the CountUp and Google Maps Blocks in all versions up to, and including, 2.18.0 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 Elements Plus! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's Image Comparison, HotSpot Plus, and Google Maps widgets in all versions up to, and including, 2.16.4 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 Elements Plus! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple widget link URLs in all versions up to, and including, 2.16.2 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
