Frappe: >> Erpnext >> 15.83.2 Security Vulnerabilities
An SSTI (Server-Side Template Injection) vulnerability exists in the get_terms_and_conditions method of Frappe ERPNext through 15.89.0. The function renders attacker-controlled Jinja2 templates (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 Terms and Conditions document can inject arbitrary Jinja expressions into the terms field, resulting in server-side code execution within a restricted but still unsafe context. This vulnerability can be used to leak database information.

An SSTI (Server-Side Template Injection) vulnerability exists in the get_dunning_letter_text method of Frappe ERPNext through 15.89.0. The function renders attacker-controlled Jinja2 templates (body_text) 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 configure Dunning Type and its child table Dunning Letter Text can inject arbitrary Jinja expressions, resulting in server-side code execution within a restricted but still unsafe context. This can leak database information.

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.

In ERPNext v15.83.2 and Frappe Framework v15.86.0, improper validation of uploaded SVG avatar images allows attackers to embed malicious JavaScript. The payload executes when an administrator clicks the image link to view the avatar, resulting in stored cross-site scripting (XSS). Successful exploitation may lead to account takeover, privilege escalation, or full compromise of the affected ERPNext instance.
