Server-Side Request Forgery (SSRF)

In a Server-Side Request Forgery (SSRF) attack, the attacker abuses functionality on the server to read or update internal resources. By supplying or modifying a URL that the server-side code processes, the attacker can reach internal services, read cloud metadata, and access systems that are not exposed to the internet.

SSRF has become one of the highest-impact vulnerability classes in modern cloud environments. Accessing the cloud metadata endpoint (http://169.254.169.254) from an SSRF can yield temporary IAM credentials, leading to full cloud account compromise. Even in non-cloud environments, SSRF enables port scanning of internal networks, accessing internal admin panels, and reaching databases or caches that trust requests from localhost.

Attackers use a wide range of bypass techniques to defeat SSRF filters: DNS rebinding, IP address encoding variations (decimal, octal, hex), URL parser inconsistencies, IPv6 representations, and redirect chains. Partial SSRF — where the attacker controls only part of the URL — can still be exploitable through open redirects or URL fragment abuse.

SSRF commonly appears in webhook integrations, URL preview features, PDF generators, image processors, and any functionality that fetches remote resources on behalf of the user.

This page collects SSRF research, bypass techniques, cloud exploitation methods, and real-world writeups from bug bounty programs and security research.

2026-07-05 2026CYBER MIND SPACE: Your firewall is useless... If your own server becomes the attacker. That's SSRF. #CyberSecurity #SSRF #AppSec beginnerServer-Side Request Forgery (SSRF) is a critical cybersecurity vulnerability where an attacker exploits an application to make the server send requests to an unintended location. This bypasses firewalls, as the malicious request originates from within the trusted network. Attackers can use SSRF to access internal systems, cloud metadata, or even trigger actions on other servers. The content highlights that even with robust firewalls, an SSRF vulnerability can render them ineffective if the server itself becomes the attacker's tool.

They exploited an open redirect vulnerability in the `/product/nextProduct?path=` parameter. This redirect was then followed by a stock checker, allowing them to access the admin panel successfully. The techniques used highlight the risks of open redirect vulnerabilities when coupled with internal services.
2026-07-04 2026ZOWEH: SSRF LAB 5 SOLVED: SSRF with filter bypass via open redirection Goal: Bypass whitelist to access internal admin panel Method: Chain SSRF with open redirect vulnerability #SSRF #BugBounty intermediateThis write-up details the solution to ZOWEH's SSRF Lab 5, which involves bypassing a whitelist to access an internal admin panel. The method used is chaining a Server-Side Request Forgery (SSRF) vulnerability with an open redirection flaw. This technique successfully circumvented the whitelist's restrictions. The post is tagged with #SSRF and #BugBounty, indicating its relevance to security research and bug bounty hunting.
2026-07-04 2026ZOWEH: BLACKLIST vs WHITELIST - MASTERED: | Filter | Bypass Method | |--------|---------------| | Blacklist | Encoding IP variations | | Whitelist | URL parsing tricks fragments | Lesson: Whitelists can be bypassed with careful URL manipulation #SSRF #CyberSecurity intermediateThis content explains two security filtering methods: blacklisting and whitelisting. Blacklists block known malicious inputs, which can be bypassed using encoding or IP variations. Whitelists, on the other hand, only allow specific inputs. However, even whitelists can be vulnerable to bypass techniques, particularly through clever URL parsing tricks and fragments. The key takeaway is that whitelists are not foolproof and can be circumvented with careful manipulation, highlighting a vulnerability in Server-Side Request Forgery (SSRF) attacks.

Frequently Asked Questions

What is SSRF and why is it critical?
Server-Side Request Forgery (SSRF) tricks the server into making HTTP requests to unintended destinations. It is critical because it can access internal services, cloud metadata endpoints (169.254.169.254), and private networks that are not reachable from the internet, potentially leading to full cloud account compromise.
What are common SSRF bypass techniques?
Common bypasses include DNS rebinding, IP encoding tricks (decimal, octal, hex, IPv6), URL parser inconsistencies between the filter and the HTTP library, open redirect chains, and alternative URL schemes. Attackers also use shortened URLs and domain names that resolve to internal IPs.
Where does SSRF commonly appear?
SSRF is frequently found in webhook integrations, URL preview and unfurling features, PDF and screenshot generators, image/file processing pipelines, and any functionality where the application fetches a remote resource based on user-supplied URLs.
