Although Frappe uses a custom SandboxedEnvironment, several dangerous globals such as frappe.db.sql are still available in the execution context via get_safe_globals(). An authenticated attacker with access to create or modify a Contract Template can inject arbitrary Jinja expressions into the contract_terms field, resulting in server-side code execution within a restricted but still unsafe context. This vulnerability can be used to leak database information."}, {"lang": "es", "value": "Una vulnerabilidad SSTI (Server-Side Template Injection) existe en el m\u00e9todo get_contract_template de Frappe ERPNext hasta la versi\u00f3n 15.89.0.
