Summary

Server-Side Template Injection (SSTI) vulnerability in the Print Format rendering mechanism of Frappe ERPNext through 15.89.0. An authenticated attacker with permission to create or modify a Print Format can inject malicious Jinja expressions into the html field, which when triggered via the get_html_and_style() API leads to information disclosure from the database, such as database version, schema, or sensitive values.

Risk Assessment

An attacker can access confidential data stored in the ERPNext database, potentially leading to a breach of confidentiality and integrity of organizational data.

Recommendation

Update ERPNext to the latest version where the vulnerability is fixed. Restrict permissions to create or modify Print Formats to trusted users only.

Original NVD description (English source)

A Server-Side Template Injection (SSTI) vulnerability exists in the Frappe ERPNext through 15.89.0 Print Format rendering mechanism. Specifically, the API frappe.www.printview.get_html_and_style() triggers the rendering of the html field inside a Print Format document using frappe.render_template(template, doc) via the get_rendered_template() call chain. Although ERPNext wraps Jinja2 in a SandboxedEnvironment, it exposes sensitive functions such as frappe.db.sql through get_safe_globals(). An authenticated attacker with permission to create or modify a Print Format can inject arbitrary Jinja expressions into the html field. Once the malicious Print Format is saved, the attacker can call get_html_and_style() with a target document (e.g., Supplier or Sales Invoice) to trigger the render process. This leads to information disclosure from the database, such as database version, schema details, or sensitive values, depending on the injected payload. Exploitation flow: Create a Print Format with SSTI payload in the html field; call the get_html_and_style() API; triggers frappe.render_template(template, doc) inside get_rendered_template(); leaks database information via frappe.db.sql or other exposed globals.
