CVE-2026-42175 (opens in a new tab)How to fix?
Upgrade requests-hardened to version 1.2.1 or higher.
Overview
requests-hardened is an A library that overrides the default behaviors of the requests library, and adds new security features.
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the URL filtering process. An attacker can access internal services and potentially exfiltrate sensitive information by supplying specially crafted URLs that target IP addresses within the RFC 6598 Shared Address Space (100.64.0.0/10).
Note: This is only exploitable if the deployment uses the affected CIDR range for internal networking.
