Administrative command execution via unsafe Smarty evaluation
Published May 13, 2026 · Updated May 13, 2026
Server-side template injection in CubeCart before 6.7.0 allows remote authenticated users with admin access to execute OS commands. The email and invoice handlers pass raw POST content to Smarty fetch calls, while document and contact handlers store unsanitized templates for later evaluation. Administrative access is required; stored attacks also require Parse Smarty Tags and a storefront request, while email payloads execute on save.
