Title
Scheduler Widget <= 0.1.6 - Insecure Direct Object Reference to Authenticated (Subscriber+) Arbitrary Event Modification
Summary
The Scheduler Widget plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 0.1.6. This is due to the `scheduler_widget_ajax_save_event()` function lacking proper authorization checks and ownership verification when updating events. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify any event in the scheduler via the `id` parameter granted they have knowledge of the event ID.

CVE-2026-1992 (GCVE-0-2026-1992)

Vulnerability from cvelistv5 – Published: 2026-03-11 09:25 – Updated: 2026-03-11 13:30

Title
ExactMetrics 8.6.0 - 9.0.2 - Authenticated (Custom) Insecure Direct Object Reference to Arbitrary Plugin Installation
Summary
The ExactMetrics – Google Analytics Dashboard for WordPress plugin is vulnerable to Insecure Direct Object Reference in versions 8.6.0 through 9.0.2. This is due to the `store_settings()` method in the `ExactMetrics_Onboarding` class accepting a user-supplied `triggered_by` parameter that is used instead of the current user's ID to check permissions. This makes it possible for authenticated attackers with the `exactmetrics_save_settings` capability to bypass the `install_plugins` capability check by specifying an administrator's user ID in the `triggered_by` parameter, allowing them to install arbitrary plugins and achieve Remote Code Execution. This vulnerability only affects sites on which administrator has given other user types the permission to view reports and can only be exploited by users of that type.

CVE-2026-2028 (GCVE-0-2026-2028)

Vulnerability from cvelistv5 – Published: 2026-04-24 03:27 – Updated: 2026-04-24 13:59

Title
Maxi Blocks <= 2.1.8 - Missing Authorization to Authenticated (Author+) Media File Deletion via 'old_media_src' Parameter
Summary
The MaxiBlocks Builder plugin for WordPress is vulnerable to arbitrary media file deletion due to insufficient file ownership validation on the 'maxi_remove_custom_image_size' AJAX action in all versions up to, and including, 2.1.8. This makes it possible for authenticated attackers, with Author-level access and above, to delete arbitrary files in the wp-content/uploads directory, including files uploaded by other users and administrators.

CVE-2026-21447 (GCVE-0-2026-21447)

Vulnerability from cvelistv5 – Published: 2026-01-02 20:15 – Updated: 2026-01-02 21:30

Title
Bagisto has IDOR in Customer Order Reorder Functionality
Summary
Bagisto is an open source laravel eCommerce platform. Prior to version 2.3.10, an Insecure Direct Object Reference vulnerability in the customer order reorder function allows any authenticated customer to add items from another customer's order to their own shopping cart by manipulating the order ID parameter. This exposes sensitive purchase information and enables potential fraud. Version 2.3.10 patches the issue.
