2026-04-22 2026SSRF Guard Bypass via Full-Form IPv4-Mapped IPv6 Literal intermediateLibrary advisory detailing an SSRF protection bypass vulnerability in OpenClaw's `ssrf.ts` component. Versions up to `2026.2.13` are affected by CWE-918, where full-form IPv4-mapped IPv6 literals like `0:0:0:0:0:ffff:7f00:1` bypassed loopback and private network blocking. A fix is available in versions `2026.2.14` and later, addressed by commit `c0c0e0f9aecb913e738742f73e091f2f72d39a19`.
2026-04-22 2026Next.js Improper Middleware Redirect Handling Leads to SSRF (CVE-2025-57822) newsLibrary update addressing CVE-2025-57822 in Next.js Middleware, where improper handling of request headers passed to `NextResponse.next()` could lead to Server-Side Request Forgery (SSRF) in self-hosted applications. Versions v14.2.32 and v15.4.7 resolve this vulnerability by preventing sensitive headers from being reflected back in responses. Users with custom middleware in self-hosted environments should upgrade and verify `next()` function usage.
2026-04-22 2026Craft CMS Cloud Metadata SSRF Protection Bypass via IPv6 Resolution intermediate 3 min readAdvisory detailing a bypass of Craft CMS's GraphQL SSRF protection. The vulnerability, a bypass of CVE-2025-68437 (GHSA-x27p-wfqw-hfcc), occurs because `gethostbyname()` only resolves IPv4 addresses. When a hostname has only AAAA (IPv6) records, the function returns the hostname string itself, failing the blocklist comparison. This allows attackers with GraphQL schema permissions to steal AWS credentials by targeting the AWS IMDS IPv6 endpoint via crafted URLs.
2026-04-22 2026Axios Unrestricted Cloud Metadata Exfiltration via Header Injection Chain (CVE-2026-40175) news 2 min readLibrary vulnerability CVE-2026-40175 in Axios allows unrestricted cloud metadata exfiltration via header injection. By leveraging prototype pollution in other dependencies, attackers can trick Axios into sending CRLF-injected headers, enabling request smuggling and bypassing AWS IMDSv2 for credential theft. This critical vulnerability, affecting all versions, arises from a lack of HTTP header sanitization combined with default SSRF capabilities, with potential impacts including authentication bypass and cache poisoning.
2026-04-19 2026CVE-2025-61882 Explained: The Oracle Zero-Day Breach news 9 min readAnalysis of CVE-2025-61882, an Oracle EBS zero-day exploited by Cl0p for unauthenticated remote code execution and data theft. The attack chain involves SSRF, CRLF injection, header smuggling, unsafe XSLT processing via BI Publisher, and privilege escalation. This vulnerability, with a CVSS score of 9.8, allowed Cl0p to bypass perimeter controls and exfiltrate sensitive ERP data from numerous enterprises before Oracle released an emergency patch.

2026-04-16 2026Bypassing SSRF Filters Using r3dir intermediate 4 min readTool for bypassing SSRF filters, r3dir, enables attackers to craft malicious requests by controlling redirection targets, response status codes, and HTTP methods. It supports CORS preflight requests for headless browsers and integrates with BurpSuite via Hackvertor tags. The service can bypass weak allowlist filters and URL scheme limitations, and can manipulate HTTP methods from POST to GET using redirect status codes like 301, 302, and 303.
2026-04-16 2026The Limitations of Secure SSRF Patches: Advanced Bypasses advanced 18 min readLibrary that analyzes Server-Side Request Forgery (SSRF) bypass techniques, demonstrating how common patches like prefix allowlisting and basic hostname validation fail against crafted payloads. It highlights vulnerabilities exemplified by the ChatGPT-Next-Web case, where naive checks for `https://trusted.com` were bypassed using `@` notation or subdomain tricks like `api.mycompany.com.evil.org`. The library emphasizes the need for defense-in-depth beyond superficial checks to prevent attackers from accessing internal networks or cloud instance metadata.
2026-04-16 2026DNS Rebinding Attacks Against SSRF Protections intermediate 5 min readLibrary for detecting and exploiting DNS rebinding vulnerabilities that bypass SSRF protections. It details how applications resolve hostnames once to validate IPs against blocklists or allowlists, and then resolve again to make the actual HTTP request. This Time-of-Check to Time-of-Use (TOCTOU) flaw allows attackers to control DNS responses, redirecting requests from public IPs to sensitive internal endpoints like AWS IMDS (169.254.169.254) or internal APIs. The library covers techniques and tools like rbndr.us and whonow for setting up controllable DNS servers with zero TTL, and discusses fixes such as resolving once and connecting directly to the IP, using egress proxies like Smokescreen, or implementing network-level controls.

2026-04-10 2026Metabadger: Prevent SSRF via Automated IMDSv2 Upgrades intermediate 7 min readTool for preventing SSRF attacks on AWS EC2 by automating upgrades to Instance Metadata Service v2 (IMDSv2). Metabadger diagnoses current IMDS usage, prepares instances for v2, enables mandatory session tokens and header checks, and can disable the service where unnecessary to reduce attack surface. It assists in identifying instances using IAM roles and provides commands to discover metadata service usage and harden configurations across regions, with options to exclude specific instances or perform dry runs.
2026-04-10 2026How to Use IMDSv2 for Secure Instance Metadata Access beginner 6 min readLibrary detailing the secure implementation of AWS Instance Metadata Service version 2 (IMDSv2). It explains how IMDSv1's lack of authentication makes it vulnerable to SSRF attacks leading to credential theft, contrasting it with IMDSv2's token-based security. The resource covers enabling and enforcing IMDSv2 for new and existing instances, updating shell scripts and Python applications, and checking fleet-wide IMDSv1 usage via CloudWatch metrics and AWS CLI commands.

2026-04-10 2026AWS Defense in Depth Against SSRF with EC2 IMDS intermediate 8 min readLibrary for enhancing the EC2 Instance Metadata Service (IMDS) to defend against open firewalls, reverse proxies, and SSRF vulnerabilities. IMDSv2 introduces session-based authentication requiring HTTP PUT requests to initiate a session and obtain a secret token, which then must be included in subsequent requests. This approach effectively mitigates open WAFs, open reverse proxies by checking for `X-Forwarded-For` headers, and many SSRF vulnerabilities by requiring both a PUT request and a valid session token. A final layer of defense against misconfigured layer-3 firewalls and NAT devices is achieved by setting the packet TTL to 1, preventing the session token from leaving the instance. → aws.amazon.com
2026-04-10 2026CVE-2025-51591: SSRF Exploit Targets AWS Instance Metadata Service news 2 min readWriteup of CVE-2025-51591, a critical SSRF vulnerability targeting AWS Instance Metadata Service (IMDS). This exploit allows attackers to steal temporary IAM credentials, leading to unauthorized AWS resource access, privilege escalation, and lateral movement within cloud environments. Organizations using EC2 instances with vulnerable applications accepting user-controlled URLs are at risk. Mitigation involves enabling IMDSv2, auditing applications for SSRF flaws, enforcing least privilege IAM roles, implementing network restrictions, and monitoring CloudTrail logs.

2026-04-10 2026CVE-2026-35572: SSRF in ChurchCRM news 3 min readWriteup of CVE-2026-35572, a Server-Side Request Forgery (SSRF) vulnerability in ChurchCRM versions prior to 6.5.3. This flaw allows attackers to inject crafted URLs into the Referer header, forcing the server to make outbound HTTP/HTTPS requests to attacker-controlled hosts. Exploitation can lead to information disclosure or interaction with internal network resources. The vulnerability is fixed in ChurchCRM version 6.5.3. → radar.offseq.com
2026-04-10 2026CVE-2026-34936: SSRF in PraisonAI news 3 min readWriteup detailing CVE-2026-34936, a Server-Side Request Forgery (SSRF) vulnerability in MervinPraison's PraisonAI multi-agent teams system. Versions prior to 4.5.90 are affected due to the `passthrough()` and `apassthrough()` functions accepting uncontrolled `api_base` parameters, which are then passed to `httpx.Client.request()` without proper validation. This allows attackers to compel the server to make requests to arbitrary internal or external hosts, potentially leading to information disclosure from protected network resources. The issue was patched in version 4.5.90. → radar.offseq.com
