WordPress Plugin: opening-hours: CVE-2023-25067: Cross-Site Request Forgery (CSRF)

The We’re Open! plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.45. This is due to missing or incorrect nonce validation on the admin_ajax function called via the we_are_open_admin_ajax AJAX action. This function triggers multiple cases (update, delete, google_business_credentials, google_data, google_business, separators, logo-delete, logo_delete, logo-remove, logo_remove, logo, structured-data, structured_data, google_data_preview, custom-styles, custom_styles clear, cache, clear-cache, clear_cache, and reset). This makes it possible for unauthenticated attackers to perform unauthorized administrative actions via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
