CVE-2026-82666Public exploitNetwork attack vectorHinoki check available

Superadmin code execution via unsandboxed Blade preview

Published Aug 31, 2026 · Updated Aug 31, 2026

Code injection in Yao Jingang GEOFlow 2.0 and 2.1.0 allows remote authenticated users to execute PHP code through a crafted theme preview. The preview method in SiteThemeEditorController passes the editable blade value directly to Blade::render without sandboxing or a safe-feature allowlist. A superadmin account or hijacked superadmin session is required, and injected PHP runs with the web application's privileges.
