CVE-2026-85040Public exploitNetwork attack vectorHinoki check available

Authenticated command execution via customCode evaluation

Published Sep 3, 2026 · Updated Sep 3, 2026

OS command injection in CRMEB 6.0 allows remote authenticated users to execute commands through the custom scheduled-task save endpoint. The save handler passes the customCode field to PHP eval after applying an isSafePhpCode denylist that does not contain executable input. Reachability requires high-privilege administration access, APP_DEBUG enabled, and the configured developer password; commands run with the web process's access.
