GET /api/Image?url=https://example.com/image.png HTTP/1.1 The server code (simplified) looks like: owasp juice shop ssrf
SSRF occurs when an application fetches a remote resource based on user-supplied input without proper validation. In Juice Shop, the vulnerability is deliberately placed to educate developers on risks like internal network scanning, localhost access, and cloud metadata endpoint extraction. 2.1 Vulnerable Endpoint The primary SSRF vector in Juice Shop (version 14+) is the /api/Image endpoint. This endpoint accepts a URL parameter and attempts to fetch an image from that location. http://[::1]:3000/encryptionkey
The challenge is solved when the student successfully extracts encryptionkey.txt . The OWASP Juice Shop SSRF challenge provides a realistic, hands-on example of how an innocent-looking image fetch endpoint can become a gateway to internal resources. By exploiting it, attackers can read local files, scan internal networks, and steal cloud credentials. Mitigation requires strict allowlisting, network controls, and never trusting user-supplied URLs. This endpoint accepts a URL parameter and attempts
