CVE-2024-7647
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe OTA Sync Booking Engine Widget plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.2.7. This is due to missing or incorrect nonce validation on the otasync_widget_settings_fnc() function. This makes it possible for unauthenticated attackers to update the plugin's settings and inject malicious scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
