CVE-2026-93836
The WPC Product Bundles for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'qty' parameter in all versions up to, and including, 8.6.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The float cast used during quantity validation allows a numeric-prefixed payload such as '1<img src=x onerror=...>' to pass validation while retaining its malicious HTML, which is then stored verbatim in order item metadata under the '_woosb_ids' key.

CVE-2026-93778
The WP Yelp Review Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Yelp Review Text (imported via wpyelp_download_source) in all versions up to, and including, 9.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The malicious payload originates from an anonymous Yelp reviewer on a public platform and requires no WordPress account; it is introduced into the database during the site administrator's ordinary use of the plugin's Download Reviews feature, making the effective attacker unauthenticated.

CVE-2026-92969
The HUSKY – Products Filter for WooCommerce Professional plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 1.4.4 via the 'shortcode' parameter parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. This vulnerability is exploitable by unauthenticated users because the only access control is a nonce check against woof_front_nonce, which is publicly emitted into inline JavaScript on every front-end page and is therefore obtainable by any site visitor without authentication.

CVE-2026-92235
The The WP Ultimate Review plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 2.4.2. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for authenticated attackers, with subscriber-level access and above, to execute arbitrary shortcodes.

CVE-2026-6922
The WP Table Builder – Drag & Drop Table Builder plugin for WordPress is vulnerable to Incorrect Authorization in all versions up to, and including, 2.2.1. This is due to an operator precedence bug in the post-type guard within the trash_table_bulk() and restore_table_bulk() functions that causes the guard to never fire, combined with a permission callback that only verifies plugin role membership without per-post-type or ownership checks. This makes it possible for authenticated attackers, with subscriber-level access and above, to trash or restore any post, page, or custom post type on the site by supplying arbitrary post IDs.
