Executive Summary

This vulnerability is a Server-Side Request Forgery (SSRF) in Soft Serve versions prior to 0.11.1. It occurs because webhook URLs are not properly validated, allowing repository administrators to create webhooks that can target internal services, private networks, and cloud metadata endpoints. This can lead to unauthorized access or interaction with internal resources.

Impact Analysis

The vulnerability can allow an attacker with repository administrator privileges to make the server send requests to internal or private network services, potentially exposing sensitive information or enabling further attacks. It can lead to high confidentiality impact, limited integrity impact, and limited availability impact as indicated by the CVSS score.

Mitigation Strategies

Upgrade Soft Serve to version 0.11.1 or later, as this version fixes the SSRF vulnerability by validating webhook URLs. Additionally, review and restrict webhook configurations to prevent targeting internal services, private networks, or cloud metadata endpoints.
