Vulnerability Summary

Frappe is a full-stack web application framework. Prior to 15.86.0 and 14.99.2, a certain endpoint was vulnerable to error-based SQL injection due to lack of validation of parameters. Some information like version could be retrieved. This vulnerability is fixed in 15.86.0 and 14.99.2.

Why is this Critical?

This vulnerability allows attackers to bypass security boundaries. If successfully exploited, malicious actors could gain unauthorized access to sensitive data, execute arbitrary code, or disrupt critical services. For enterprise environments, this poses a severe risk of data breaches and compliance violations (GDPR/HIPAA).

Technical Context: SQL Injection

This issue involves SQL Injection (SQLi), one of the most dangerous web vulnerabilities. It occurs when user input is not properly sanitized before being passed to a database query. Attackers can use this to dump entire databases or bypass login screens.

Security Best Practices

• Patch Management: Automate security updates to reduce the exposure window.
• Network Segmentation: Isolate critical services to prevent lateral movement.
• Traffic Monitoring: Use intrusion detection systems to spot exploitation attempts.
