Plesk Extension Node Js Toolkit
Monthly
Remote authenticated users of the Plesk 'Ruby' (before 1.6.6) and 'Node.js Toolkit' (before 2.5.0) extensions can inject arbitrary shell directives into statically generated application startup code via custom environment variables, resulting in code execution with root privileges on the Plesk server. The flaw is a classic static code injection (CWE-96): user-supplied values are written verbatim into persisted configuration/startup files rather than being escaped. No public exploit code or CISA KEV listing is present in the provided intelligence, and no EPSS score was supplied, so exploitation appears limited to actors who already hold a valid low-privileged Plesk account; vendor patches are available.
