requests-hardened: Server-Side Request Forgery (SSRF) in requests-hardened RFC 6598

requests-hardened is a library that overrides the default behaviors of the requests library, and adds new security features. Prior to , the SSRF protection in requests-hardened fails to block IP addresses within the RFC 6598 Shared Address Space (100.64.0.0/10). An attacker who can supply arbitrary URLs to requests-hardened could exploit this gap to access internal services hosted within 100.64.0.0/10. This is for example relevant in environments such as AWS EKS where 100.64.0.0/10 is commonly used as the default pod CIDR. The impact is environment-dependent, deployments that utilize the affected CIDR range for internal networking are exposed to SSRF bypass, while others may not be affected. This vulnerability is fixed in .

Postiz: TOCTOU DNS rebinding bypasses all SSRF URL validation paths

Postiz is an AI social media scheduling tool. From version 2.16.6 to before version 2.21.7, all SSRF protections added in v2.21.4–v2.21.6 share a fundamental TOCTOU (Time-of-Check-Time-of-Use) vulnerability: isSafePublicHttpsUrl() resolves DNS to validate the target IP, but subsequent fetch() calls resolve DNS independently. An attacker controlling a DNS server can exploit this gap via DNS rebinding to redirect requests to internal network addresses. This issue has been patched in version 2.21.7.

WWBN AVideo is an open source video platform. In 29.0 and earlier, EpgParser.php, plugin/AI/receiveAsync.json.php, and other locations do not use the $resolvedIP out-param of isSSRFSafeURL() for DNS pinning via CURLOPT_RESOLVE, opening DNS-rebinding TOCTOU.

Next.js Improper Middleware Redirect Handling Leads to SSRF

Next.js is a React framework for building full-stack web applications. Prior to versions 14.2.32 and 15.4.7, when next() was used without explicitly passing the request object, it could lead to SSRF in self-hosted applications that incorrectly forwarded user-supplied headers. This vulnerability has been fixed in Next.js versions 14.2.32 and 15.4.7. All users implementing custom middleware logic in self-hosted environments are strongly encouraged to upgrade and verify correct usage of the next() function.
