CVE-2026-56843: CWE-522 Insufficiently Protected Credentials in Webpros PleskCVE-2026-56843
0

CVE-2026-56843 is a critical vulnerability in WebPros Plesk before version 18.0.78.4 where incorrect authorization in the XML-RPC API allows low-privileged authenticated users to access domains they do not own. This flaw bypasses ownership enforcement for certain lookup filters and legacy protocol schema validation, leading to cross-tenant disclosure of FTP credentials stored in cleartext. Exploiting this can enable attackers to execute code as another tenant's system user.
