Frappe Framework development builds contain an authorization flaw in the render_jinja_template endpoint that allows low-privileged users to render arbitrary Jinja templates by supplying raw template strings. Attackers with print permission on any document can execute arbitrary SELECT statements against unrelated tables, including reading password hashes from the __Auth table.
