CVE-2022-2371: Yaycommerce Yaysmtp

Medium severity, CVSS 5.4. EPSS: 0.6% chance of exploitation in the next 30 days.

The YaySMTP WordPress plugin before 2.2.1 does not have proper authorisation when saving its settings, allowing users with a role as low as subscriber to change them, and use that to conduct Stored Cross-Site Scripting attack due to the lack of escaping in them as well.
