In Go before 1.15.13 and 1.16.x before 1.16.5, some configurations of ReverseProxy (from net/http/httputil) result in a situation where an attacker is able to drop arbitrary headers.

The RepairBuddy – Repair Shop CRM & Booking Plugin for WordPress is vulnerable to unauthorized access in all versions up to, and including, 4.1132. The plugin exposes two AJAX handlers that, when combined, allow any authenticated user to modify admin-level plugin settings. First, the wc_rb_get_fresh_nonce() function (registered via wp_ajax and wp_ajax_nopriv hooks) allows any user to generate a valid WordPress nonce for any arbitrary action name by simply providing the nonce_name parameter, with no capability checks. Second, the wc_rep_shop_settings_submission() function only verifies the nonce (wcrb_main_setting_nonce) but performs no current_user_can() capability check before updating 15+ plugin options via update_option(). This makes it possible for authenticated attackers, with subscriber-level access and above, to modify all plugin configuration settings including business name, email, logo, menu label, GDPR settings, and more by first minting a valid nonce via the wc_rb_get_fresh_nonce endpoint and then calling the settings submission handler.

Missing Authorization vulnerability in themebeez Cream Blog cream-blog allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Cream Blog: from n/a through <= 2.1.7.

The Punnel – Landing Page Builder plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 1.3.1. The save_config() function, which handles the 'punnel_save_config' AJAX action, lacks any capability check (current_user_can()) and nonce verification. This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the plugin's entire configuration including the API key via a POST request to admin-ajax.php. Once the API key is known (because the attacker set it), the attacker can use the plugin's public API endpoint (sniff_requests() at /?punnel_api=1) — which only validates requests by comparing a POST token against the stored api_key — to create, update, or delete arbitrary posts, pages, and products on the site.

The PZ Frontend Manager plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.0.6. The pzfm_user_request_action_callback() function, registered via the wp_ajax_pzfm_user_request_action action hook, lacks both capability checks and nonce verification. This function handles user activation, deactivation, and deletion operations. When the 'dataType' parameter is set to 'delete', the function calls wp_delete_user() on all provided user IDs without verifying that the current user has the appropriate permissions. Notably, the similar pzfm_remove_item_callback() function does check pzfm_can_delete_user() before performing deletions, indicating this was an oversight. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary WordPress users (including administrators) by sending a crafted request to the AJAX endpoint.

The WP-Chatbot for Messenger plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.9. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to overwrite the site's MobileMonkey API token and company ID options, which can be used to hijack chatbot configuration and redirect visitor conversations to an attacker-controlled MobileMonkey account.

The Canto plugin for WordPress is vulnerable to Missing Authorization in all versions up to, and including, 3.1.1 via the `/wp-content/plugins/canto/includes/lib/copy-media.php` file. This is due to the file being directly accessible without any authentication, authorization, or nonce checks, and the `fbc_flight_domain` and `fbc_app_api` URL components being accepted as user-supplied POST parameters rather than read from admin-configured options. Since the attacker controls both the destination server and the `fbc_app_token` value, the entire fetch-and-upload chain is attacker-controlled — the server never contacts Canto's legitimate API, and the uploaded file originates entirely from the attacker's infrastructure. This makes it possible for unauthenticated attackers to upload arbitrary files (constrained to WordPress-allowed MIME types) to the WordPress uploads directory. Additional endpoints (`detail.php`, `download.php`, `get.php`, `tree.php`) are also directly accessible without authentication and make requests using a user-supplied `app_api` parameter combined with an admin-configured subdomain.
