Description

An issue was discovered in Frappe ERPNext through 15.89.0. Function get_outstanding_reference_documents() at erpnext/accounts/doctype/payment_entry/payment_entry.py is vulnerable to SQL Injection. It allows an attacker to extract arbitrary data from the database by injecting SQL payloads via the to_posting_date parameter, which is directly interpolated into the query without proper sanitization or parameter binding.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
