CVE-2026-58046 is a blind SQL injection vulnerability in the Plesk XML-RPC API affecting Plesk versions prior to 18.0.79.4. The flaw is caused by improper neutralization of attacker-controlled input in XML-RPC requests, allowing a remote authenticated user with low privileges, including customer- or reseller-level access, to execute arbitrary SQL queries against the Plesk database. Successful exploitation enables extraction of arbitrary database contents and can expose sensitive administrative data, creating a path to full compromise of the Plesk panel.
