DescriptionGitHub Advisory

Frappe is a full-stack web application framework. Prior to 15.84.0 and 14.99.0, a specially crafted request made to a certain endpoint could result in SQL injection, allowing an attacker to extract information they wouldn't otherwise be able to. This vulnerability is fixed in 15.84.0 and 14.99.0.

Executive ViewAI

Why It Matters

A critical SQL injection vulnerability in Frappe framework versions up to 15.84.0 allows unauthenticated attackers to potentially extract sensitive data, modify records, or compromise system integrity. Organizations using affected Frappe versions face immediate risk of data breach and operational disruption, particularly if customer or financial data is stored in these systems.

Business Impact: Severe

Compensating Controls

Deploy Web Application Firewall (WAF) with SQL injection detection signatures; implement network segmentation to restrict database access; enable database activity monitoring and alerting; disable or restrict Frappe features known to be exploitable until patch is available; enforce principle of least privilege on database accounts; conduct daily review of application and database logs for exploitation attempts; consider running affected systems in read-only mode if operationally feasible.
