The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data passed via the "subscribeEmail" function in the “includes/views/admin-subscribers.php” script. A remote attacker can inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
3) Cross-site request forgery (CVE-ID: CVE-2019-17235)
CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

4) Improper Privilege Management (CVE-ID: CVE-2019-17234)
CWE-ID: CWE-269 - Improper Privilege Management
CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to escalate privilege on the target system.
The vulnerability exists due to the "deleteTemplate" function in the “includes/class-coming-soon-creator.php” script does not check the user capabilities and lacks a security nonce. A remote attacker can execute that function to delete any file or folder on the website.
5) Improper access control (CVE-ID: N/A)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N]
