|---|---|---|---|---|---|---|---|
| CVE-2024-5441 | Hig | 0.59 | 8.8 | 0.20 | Jul 9, 2024 | The Modern Events Calendar plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the set_featured_image function in all versions up to, and including, 7.11.0. This makes it possible for authenticated attackers, with subscriber access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The plugin allows administrators (via its settings) to extend the ability to submit events to unauthenticated users, which would allow unauthenticated attackers to exploit this vulnerability. | |
| CVE-2023-4021 | Med | 0.29 | 4.4 | 0.00 | Oct 20, 2023 | The Modern Events Calendar lite plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Google API key and Calendar ID in versions up to, but not including, 7.1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled. | |
| CVE-2021-4458 | 0.00 | — | 0.00 | Jul 12, 2025 | The Modern Events Calendar Lite plugin for WordPress is vulnerable to SQL Injection via the 'id' parameter of the 'wp_ajax_mec_load_single_page' AJAX action in all versions up to, and including, 6.3.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is only exploitable on sites with addslashes disabled. | ||
| CVE-2024-6522 | 0.00 | — | 0.01 | Aug 7, 2024 | The Modern Events Calendar plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 7.12.1 via the 'mec_fes_form' AJAX function. This makes it possible for authenticated attackers, with Subscriber-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. | ||
| CVE-2022-30533 | 0.00 | — | 0.00 | Jun 16, 2022 | Cross-site scripting vulnerability in Modern Events Calendar Lite versions prior to 6.3.0 allows remote an authenticated attacker to inject an arbitrary script via unspecified vectors. |
