An SSTI (Server-Side Template Injection) vulnerability exists in the get_contract_template method of Frappe ERPNext through 15.89.0. The function renders attacker-controlled Jinja2 templates (contract_terms) using frappe.render_template() with a user-supplied context (doc). 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.
ERP is a free and open source Enterprise Resource Planning tool. In versions below 14.89.2 and 15.0.0 through 15.75.1, lack of validation of parameters left certain endpoints vulnerable to error-based SQL Injection. Some information like version could be retrieved. This issue is fixed in versions 14.89.2 and 15.76.0.
In ERPNext, versions v11.0.0-beta through v13.0.2 are vulnerable to Missing Authorization, in the chat rooms functionality. A low privileged attacker can send a direct message or a group message to any member or group, impersonating themselves as the administrator. The attacker can also read chat messages of groups that they do not belong to, and of other users.
