Frappe is a full-stack web application framework. Prior to versions 14.94.3 and 15.58.0, SQL injection could be achieved via a specially crafted request, which could allow malicious person to gain access to sensitive information. This issue has been patched in versions 14.94.3 and 15.58.0. There are no workarounds for this issue other than upgrading.
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.
