While I don't have specific information on exploits related to Nicepage, there are common vulnerabilities found in many website builders and web applications: Nicepage is a popular drag-and-drop website builder used

The most dangerous vector was the media uploader component. Nicepage allowed logged-out users (in certain configurations where front-end editing was enabled) to upload SVG files directly. SVGs are images, but they can contain malicious JavaScript.

How it worked:

Q: Is my site safe if I uninstall Nicepage? A: Not necessarily. Malicious files (SVGs, backdoors, or admin users) may remain. Uninstall Nicepage, then manually audit your uploads and users.

Q: Does the exploit affect Nicepage sites hosted on their cloud platform? A: The cloud-hosted version (nicepage.com) is less exposed because they control server configs, but user-imported templates could still carry XSS. Always scan imports. Nicepage uses custom endpoints

Q: What if I can’t update to 6.3.9 due to compatibility? A: Then disable front-end editing entirely, block REST API endpoints for non-logged-in users, and remove SVG upload capabilities via an mu-plugin.
