WordPress The Events Calendar plugin <= 6.17.4 - PHP Object Injection vulnerability

Deserialization of Untrusted Data vulnerability in Liquid Web / StellarWP The Events Calendar allows Object Injection. This issue affects The Events Calendar: from n/a through 6.17.4.

The Events Calendar <= 6.17.4 - Unauthenticated PHP Object Injection to Remote Code Execution

The The Events Calendar plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 6.17.4 via the is_safe_widget_instance function. This is due to insufficient protection in is_safe_widget_instance, which can be bypassed because PHP fires magic methods during its pre-parse, combined with enable_rendering_widget_copied() forging a valid wp_hash integrity attribute before unserialize() is reached. This makes it possible for unauthenticated attackers to execute code on the server. This is exploitable without authentication or approval because the plugin's V2 single-event template runs do_blocks() over buffered comment HTML, and WordPress returns a moderation-hash URL that allows an unauthenticated commenter to immediately view their own pending comment, delivering the injected block markup to the vulnerable code path before any moderation occurs. This does require comments to be enabled and visible on events.

The Events Calendar <= 6.17.3 - Unauthenticated Code Injection to Remote Code Execution via Widget 'classes' Map Callable Invocation

The The Events Calendar plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 6.17.3 via the parse_array function. This is due to insufficient validation of the widget 'classes' map, allowing a plain-array payload to bypass the is_safe_widget_instance() object check and reach the callable-invocation sink in Element_Classes::parse_array(). This makes it possible for unauthenticated attackers to execute code on the server. Exploitation requires that the targeted site has comments enabled on tribe_events posts and that at least one comment containing a crafted wp:legacy-widget block has been submitted, as the attack chain is triggered when do_blocks() processes the single-event HTML including the comment area.

WordPress The Events Calendar plugin 6.15.12-6.16.2 - SQL Injection vulnerability

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Liquid Web / StellarWP The Events Calendar allows Blind SQL Injection. This issue affects The Events Calendar: from 6.15.12 through 6.16.2.

The Events Calendar <= 6.15.17 - Authenticated (Author+) Arbitrary File Read via ajax_create_import

The The Events Calendar plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 6.15.17 via the 'ajax_create_import' function. This makes it possible for authenticated attackers, with Author-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.

The Events Calendar <= 6.13.2 - Authenticated (Contributor+) DOM-Based Stored Cross-Site Scripting

The The Events Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘data-date-*’ parameters in all versions up to, and including, 6.13.2 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 Events Calendar <= 6.15.9 - Sysinfo Key Incorrect Comparison to Unauthenticated Sensitive Information Exposure

The Events Calendar plugin for WordPress is vulnerable to information disclosure in versions up to, and including, 6.15.9. The sysinfo REST endpoint compares the provided key to the stored opt-in key using a loose comparison, allowing unauthenticated attackers to send a boolean value and obtain the full system report whenever "Yes, automatically share my system information with The Events Calendar support team" setting is enabled.

The Events Calendar <= 6.15.13 - Missing Authorization to Authenticated (Subscriber+) Data Migration Control

The The Events Calendar plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the 'start_migration', 'cancel_migration', and 'revert_migration' functions in all versions up to, and including, 6.15.13. This makes it possible for authenticated attackers, with subscriber level access and above, to start, cancel, or revert the Custom Tables V1 database migration, including dropping the custom database tables entirely via the revert action.

The Events Calendar <= 6.15.9 - Missing Authorization to Authenticated (Subscriber+) Draft Event Title/QR Code Exposure

The The Events Calendar plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the 'tec_qr_code_modal' AJAX endpoint in all versions up to, and including, 6.15.9. This makes it possible for authenticated attackers, with Subscriber-level access and above, to view draft event names and generate/view QR codes for them.

The Events Calendar <= 6.15.16 - Improper Authorization to Authenticated (Contributor+) Event/Organizer/Venue Update/Trash via REST API

The The Events Calendar plugin for WordPress is vulnerable to unauthorized modification of data and loss of data due to an improper capability check on the 'can_edit' and 'can_delete' function in all versions up to, and including, 6.15.16. This makes it possible for authenticated attackers, with Contributor-level access and above, to update or trash events, organizers and venues via REST API.

The Events Calendar 6.15.1.1 - 6.15.9 - Unauthenticated SQL Injection via s

The The Events Calendar plugin for WordPress is vulnerable to blind SQL Injection via the 's' parameter in versions 6.15.1.1 to 6.15.9 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 Calendar <= 6.2.8.2 - Unauthenticated Sensitive Information Exposure

The The Events Calendar plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 6.2.8.2 via the route function hooked into wp_ajax_nopriv_tribe_dropdown. This makes it possible for unauthenticated attackers to extract potentially sensitive data including post titles and IDs of pending, private and draft posts.

The Events Calendar <= 6.6.4 - Unauthenticated SQL Injection

The The Events Calendar plugin for WordPress is vulnerable to SQL Injection via the 'order' parameter of the 'tribe_has_next_event' function in all versions up to, and including, 6.6.4 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. Only sites that have manually added tribe_has_next_event() will be vulnerable to this SQL injection.

The Events Calendar <= 6.6.3 - Unauthenticated Stored Cross-Site Scripting

The The Events Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via RSVP name field in all versions up to, and including, 6.6.3 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 Events Calendar < 6.8.2.1 - Unauthenticated Password Protected Event Disclosure

The Events Calendar WordPress plugin before 6.8.2.1 is missing access checks in the REST API, allowing for unauthenticated users to access information about password protected events.

The Events Calendar < 6.6.4 - Admin+ Stored XSS

The Events Calendar WordPress plugin before 6.6.4 does not sanitise and escape some of its settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example in multisite setup).

The Events Calendar < 6.4.0.1 - Reflected XSS

The Events Calendar WordPress plugin before 6.4.0.1 does not properly sanitize user-submitted content when rendering some views via AJAX.

The Events Calendar < 6.2.8.1 - Unauthenticated Arbitrary Password Protected Post Read

The Events Calendar WordPress plugin before 6.2.8.1 discloses the content of password protected posts to unauthenticated users via a crafted request

The the-events-calendar plugin before 4.8.2 for WordPress has XSS via the tribe_paged URL parameter.
