The Eventin – Event Calendar, Tickets, Registration, Booking & WooCommerce plugin for WordPress is vulnerable to Privilege Escalation in all versions up to, and including, 4.1.23. This is due to the `PermissionManager::manage_permissions()` function being registered as a callback on WordPress core's `map_meta_cap` filter and unconditionally returning the always-true `'exist'` primitive for every capability check whenever the evaluated user ID is 1, without scoping this behavior to plugin-specific capabilities. This makes it possible for authenticated attackers whose account is user ID 1, even subscribers, to pass every WordPress capability check, including `manage_options`, `edit_plugins`, `edit_themes`, `promote_users`, and `update_core`, thereby elevating their privileges to administrator-equivalent power and achieving full site takeover, including remote code execution via the plugin and theme editors. Exploitation is only impactful when user ID 1 has been deliberately demoted to a lower-privilege role as a common administrator-account hardening practice; on default installations where user ID 1 retains the administrator role, no incremental privilege gain occurs.

The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'etn_shedule_objective' schedule_slot Parameter in all versions up to, and including, 4.1.23 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 Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.1.17. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to view, create, update, clone, and delete notification flow event automation workflows that should be restricted to administrators.

The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.1.22 via the 'event_layout' parameter parameter. This makes it possible for authenticated attackers, with custom-level access and above, 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.

The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 4.1.22 via the 'event_layout' parameter parameter. This makes it possible for authenticated attackers, with contributor-level access and above, 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. The etn_manage_event capability is assigned to Contributors by default, meaning any Contributor-level user can set the malicious event_layout value via the REST API without any additional configuration.

The WP Event Solution (Eventin) plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 4.1.22 via the create_item() handler for the /wp-json/eventin/v2/orders REST endpoint. The endpoint's create_item_permissions_check() function only verifies a wp_rest nonce (which is leaked to every visitor through the etn-public script's localized_data_obj on every frontend page) and accepts a user-supplied 'status' value in prepare_item_for_database() with no whitelist validation. This makes it possible for unauthenticated attackers to create etn-order posts with status='completed' that are counted as sold by etn_get_sold_tickets_by_event(); because the auto-cleanup wp_schedule_single_event() in create_item() only fires for status='pending' orders, the forged completed orders persist indefinitely and exhaust ticket inventory.

Unauthenticated Broken Access Control in WP Event SOlution <= 4.1.22 versions.

Customer Arbitrary Content Deletion in WP Event SOlution <= 4.1.19 versions.

Customer Sensitive Data Exposure in WP Event SOlution <= 4.1.18 versions.

Unauthenticated Broken Authentication in WP Event SOlution <= 4.1.9 versions.

The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to authorization bypass due to a regression in versions from 4.0.26 up to and including 4.1.15. This is due to the plugin not properly verifying that a user is authorized to perform an action in the payment_complete() function of PaymentController.php. This makes it possible for unauthenticated attackers to mark unpaid ticket orders as completed by submitting a fabricated SureCart checkout ID or FluentCart cart hash, granting themselves paid event access, QR-code attendee tickets, and order confirmation emails without making any real payment. The wp_rest nonce required to reach the vulnerable endpoint is embedded in every public event page, meaning no WordPress session or credentials are needed to obtain it. This vulnerability represents a regression — the same function and endpoint were previously patched but the fix did not persist through subsequent releases.

The Eventin – Event Calendar, Event Registration, Tickets & Booking (AI Powered) plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'etn_faq_content' parameter in all versions up to, and including, 4.1.15 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.

Missing Authorization vulnerability in Arraytics WP Event Solution wp-event-solution allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects WP Event Solution: from n/a through 4.1.12.

Unauthenticated Broken Access Control in WP Event SOlution <= 4.1.8 versions.

Deserialization of Untrusted Data vulnerability in Arraytics Eventin wp-event-solution allows Object Injection.This issue affects Eventin: from n/a through <= 4.1.3.

The Eventin – Event Manager, Events Calendar, Event Tickets and Registrations plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'post_settings' function in all versions up to, and including, 4.0.51. This makes it possible for unauthenticated attackers to modify plugin settings. Furthermore, due to insufficient input sanitization and output escaping on the 'etn_primary_color' setting, this enables unauthenticated attackers to inject arbitrary web scripts that will execute whenever a user accesses a page where Eventin styles are loaded.

The Events Calendar, Event Booking, Registrations and Event Tickets – Eventin plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 4.0.37 via the proxy_image function. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.

Deserialization of Untrusted Data vulnerability in Arraytics Eventin wp-event-solution allows Object Injection.This issue affects Eventin: from n/a through <= 4.0.31.

The Eventin plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 4.0.34. This is due to the plugin not properly validating a user's identity or capability prior to updating their details like email in the 'Eventin\Speaker\Api\SpeakerController::update_item' function. This makes it possible for unauthenticated attackers with contributor-level and above permissions to change arbitrary user's email addresses, including administrators, and leverage that to reset the user's password and gain access to their account.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Arraytics Eventin wp-event-solution allows Reflected XSS.This issue affects Eventin: from n/a through <= 4.0.28.

Incorrect Privilege Assignment vulnerability in Arraytics Eventin wp-event-solution allows Privilege Escalation.This issue affects Eventin: from n/a through <= 4.0.26.

Relative Path Traversal vulnerability in Arraytics Eventin wp-event-solution allows Path Traversal.This issue affects Eventin: from n/a through <= 4.0.26.

The Event Manager, Events Calendar, Tickets, Registrations – Eventin plugin for WordPress is vulnerable to arbitrary file read in all versions up to, and including, 4.0.26 via the proxy_image() function. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. CVE-2025-47445 is a duplicate of this vulnerability.

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in Arraytics Eventin wp-event-solution allows PHP Local File Inclusion.This issue affects Eventin: from n/a through <= 4.0.25.
