AI Analysis
Technical Summary
This vulnerability (CVE-2026-58046) in WebPros Plesk version 18.0.79.4 is caused by improper neutralization of input in the XML-RPC API, enabling a remote authenticated user with low privileges to perform SQL injection. The injection can be leveraged to extract arbitrary data from the Plesk database, potentially resulting in complete control over the Plesk management panel. The CVSS 3.1 base score is 9.9, indicating critical severity with network attack vector, low attack complexity, low privileges required, no user interaction, and complete confidentiality, integrity, and availability impact.
Potential Impact
An attacker with low-privileged authenticated access can exploit this vulnerability to perform SQL injection, leading to unauthorized disclosure of sensitive data and full compromise of the Plesk panel. This includes potential takeover of the management interface and control over hosted services.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict access to the XML-RPC API to trusted users and monitor for suspicious activity involving authenticated low-privileged accounts.
