- Plesk for Linux
- Plesk for Windows
CVE-2021-44228 is a vulnerability in Apache Log4j which is a Java library. So, this vulnerability may affect Java-based applications only.
Plesk does not use Java internally, so Plesk is not affected by this vulnerability. Since Tomcat support in Plesk was dropped in Plesk 17.8, Plesk does not support users' Java-based applications.
