  - The Popup Builder WordPress plugin through 4.1.15 does not sanitise and escape some of its settings,
    which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks
    even when the unfiltered_html capability is disallowed (for example in multisite setup). (CVE-2023-5561)

  - Auth. Stored (contributor+) Cross-Site Scripting (XSS). (CVE-2023-38000)

  - Exposure of Sensitive Information to an Unauthorized Actor. (CVE-2023-39999)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
