    Authenticated SQL Injection in cPanel EmailTrack Leads to Root RCE
    CVE-2026-67401 is a critical SQL injection (CWE-89) in the EmailTrack component of cPanel, the widely used hosting control panel. An attacker holding any mail-enabled account on the server can reach the vulnerable component over the network with low privileges and no user interaction (CVSS: AV:N/AC:L/PR:L/UI:N), and the injection crosses a privilege boundary (Scope: Changed) to achieve remote code execution as root. Successful exploitation yields full compromise of the host — arbitrary commands as root with complete access to all hosted data — so every site, mailbox and account on an affected server is exposed. All cPanel deployments with mail enabled are potentially affected; the available data does not specify exact vulnerable version ranges, which are provided in WebPros security advisory AV26-908. Exploitation has not been confirmed in the wild (not in CISA KEV), but two public proof-of-concept exploits are already on GitHub, making near-term exploitation likely.
