Is Events Manager safe? Known vulnerabilities and latest version

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Pixelite Events Manager events-manager allows Reflected XSS.This issue affects Events Manager: from n/a through 7.4.8.

Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in Pixelite Events Manager events-manager allows Leveraging Race Conditions.This issue affects Events Manager: from n/a through 7.4.7.

Subscriber SQL Injection in Events Manager <= 7.4.6 versions.

Insertion of Sensitive Information Into Sent Data vulnerability in Pixelite Events Manager events-manager allows Retrieve Embedded Sensitive Data.This issue affects Events Manager: from n/a through 7.4.5.

The Events Manager WordPress plugin before 7.4.5 does not force the scope of its logged-in event and location search when a caller supplies their own owner value, letting a low-privileged user read other accounts' unpublished, pending or trashed event and venue content, including full street addresses.

The Events Manager WordPress plugin before 7.4.5 does not stop a ticket-update request from replacing the identifiers of the ticket it was authorized against, letting a user who can manage one event's tickets overwrite and reassign any ticket on the site to their own event.

The Events Manager - Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via event attribute values in all versions up to, and including, 7.3.3. This is due to insufficient input sanitization when storing attribute values (using only `wp_unslash()` without sanitization) and lack of output escaping when rendering the '#_ATT{key}' placeholder. This makes it possible for authenticated attackers, with Author-level access and above, or unauthenticated attackers when anonymous event submissions are enabled, to inject arbitrary web scripts that execute when any user views the affected event page.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'header_format' parameter in all versions up to, and including, 7.4.0.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The shortcode entry point sanitizes 'header_format' via wp_kses(), but the unauthenticated 'search_events_grouped' AJAX action bypasses this sanitization entirely, leaving the parameter unsanitized before it is echoed into the HTML body in output_grouped().

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 7.3.7.4 via the em_options_save function. This makes it possible for authenticated attackers, with administrator-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 stored traversal key is subsequently executed via an include_once() call that fires on every admin_init invocation — including unauthenticated admin-ajax.php requests — meaning once the malicious key is stored by an administrator, the inclusion is triggered without any further authentication or capability check.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.4.0. 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 view the titles, dates, descriptions, and location details of events and locations that administrators have marked as draft, pending, trashed, or private.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to generic SQL Injection via Stored 'meta_key' via Event/Location Duplicate Action in all versions up to, and including, 7.4.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a second-order SQL injection: an attacker first plants SQL metacharacters in a custom meta key via the standard add-meta flow (WordPress stores these verbatim in wp_postmeta), then triggers the injection by invoking the event_duplicate or location_duplicate action, which reads the stored meta keys via get_post_meta() and concatenates them unsafely into the INSERT query.

The Events Manager WordPress plugin before 7.4.1 does not properly scope its capability mapping, discarding the access control decisions WordPress already made for unrelated privileged actions, which allows unauthenticated users to change the password of, escalate to Administrator, or delete any account whose user ID happens to match the ID of one of the Events Manager WordPress plugin before 7.4.1's own posts.

The Events Manager WordPress plugin before 7.4.1 does not sanitise and escape a user-controlled value before using it in a SQL statement, allowing users with a subscriber account and above to perform SQL injection attacks and tamper with booking consent records belonging to other people.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Pixelite Events Manager events-manager allows Reflected XSS.This issue affects Events Manager: from n/a through 7.4.2.

The Events Manager WordPress plugin before 7.4 does not perform any authorization check on a REST route that serves temporarily stored file uploads, allowing unauthenticated users to retrieve another user's in-progress upload when its temporary identifier is known. The identifier is high-entropy, is disclosed only to the uploader, and the file is removed on submission or by a scheduled cleanup, so a cross-user read is not achievable by guessing alone.

The Events Manager WordPress plugin before 7.3.7 does not safely handle booking-registration data on sites using No-User-Account Booking Mode: a booker-supplied registration field is stored as booking meta and later deserialized without restricting allowed classes, enabling PHP object injection. The resulting gadget chain reaches a database query that is built without parameterisation, so an unauthenticated attacker can read arbitrary database data (e.g. user password hashes, secret keys) when the booking is later loaded.

Deserialization of Untrusted Data vulnerability in Marcus (aka @msykes) Events Manager events-manager allows Object Injection.This issue affects Events Manager: from n/a through <= 7.3.6.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'events_list_grouped' shortcode in all versions up to, and including, 7.2.2.1 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 Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Information Exposure in all versions up to, and including, 7.2.2.2 via the 'get_location' action due to insufficient restrictions on which locations can be included. This makes it possible for unauthenticated attackers to extract data from password protected, private, or draft event locations that they should not have access to.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 7.2.2.2. This is due to missing or incorrect nonce validation on the 'location_delete' action. This makes it possible for unauthenticated attackers to delete locations via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcodes in all versions up to, and including, 7.0.3 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 Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to time-based SQL Injection via the ‘orderby’ parameter in all versions up to, and including, 7.0.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘calendar_header’ parameter in all versions up to, and including, 7.0.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

Missing Authorization vulnerability in Marcus (aka @msykes) Events Manager events-manager allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Events Manager: from n/a through <= 6.6.4.1.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to time-based SQL Injection via the active_status parameter in all versions up to, and including, 6.6.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'event', 'location', and 'event_category' shortcodes in all versions up to, and including, 6.4.7.3 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.

Missing Authorization vulnerability in Pixelite Events Manager.This issue affects Events Manager: from n/a through 6.4.6.4.

Cross-Site Request Forgery (CSRF) vulnerability in Pixelite Events Manager.This issue affects Events Manager: from n/a through 6.4.7.1.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the physical location value in all versions up to, and including, 6.4.7.1 due to insufficient input sanitization and output escaping. 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.

The Events Manager – Calendar, Bookings, Tickets, and more! plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.4.7.1. This is due to missing or incorrect nonce validation on several actions. This makes it possible for unauthenticated attackers to modify booking statuses via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
