    Don’t think this will be a concern for me on the single site I am using your plugin on, but wanted to let you know Wordfence is reporting this:

    Popup Builder <= 4.1.15 – Authenticated (Admin+) Stored Cross-Site Scripting
    Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’)
    CVSS VectorCVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:N
    CVE CVE-2023-3226
    CVSS 4.4 (Medium)

    Description
    The Popup Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 4.1.15 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.
