CVE-2026-58046 is a SQL injection vulnerability in WebPros Plesk's XML-RPC API caused by improper neutralization of input. The flaw affects Plesk versions earlier than 18.0.79.4 and is exploitable by a remote authenticated user with low privileges, including customer- or reseller-level access. Successful exploitation permits blind SQL injection against the Plesk database, allowing arbitrary database reads and execution of attacker-controlled SQL queries. Because the database may contain highly sensitive panel data, including administrator credentials, exploitation can enable escalation from low-privileged panel access to full compromise of the Plesk panel and potentially the underlying server environment.
