CVE-2026-65643 is an eval-injection vulnerability in cPanel & WebHost Manager (WHM) domain-parking and addon-domain functionality. An authenticated cPanel account authorized to add parked or addon domains can create arbitrary files on the underlying server. This condition can be leveraged to execute arbitrary code in the root-user context. Affected releases include supported builds earlier than 11.110.0.141, 11.134.0.53, 11.136.0.37, and 11.138.0.2, plus WP Squared builds earlier than 11.138.1.7.

This six-file standalone Python repository contains two executable tools: exploit.py, a large authenticated exploitation and mass-scanning toolkit, and verifier.py, a smaller reporting-oriented verifier. Both use requests/urllib3; supporting files are a dependency list, README, license, and ignore rules. The exploit parses a supplied cPanel target, manages HTTP sessions, optionally routes traffic through a proxy or local Tor SOCKS service, suppresses TLS verification by default, rotates User-Agent strings, applies retry/delay/jitter behavior, and can process multiple targets concurrently. Its stated injection mechanism is to submit a parked-domain name containing backtick-delimited shell commands through cPanel JSON, form, CGI, or API2 routes. The verifier performs version checks against four cPanel/CGI paths, authenticates with supplied credentials, then tests injection and writes a JSON report. The exploit supports substantially more intrusive actions, including arbitrary commands, reverse shell requests, file actions, persistence-oriented account creation, password changes, interactive operation, and cleanup. The repository's assertions of automatic root execution should be treated as target-configuration dependent rather than proven solely by the visible material.
