CVE-2026-42175: CWE-918: Server-Side Request Forgery (SSRF) in saleor requests-hardened
CVE-2026-42175 is a Server-Side Request Forgery (SSRF) vulnerability in the requests-hardened library used by saleor. The vulnerability arises because requests-hardened fails to block IP addresses within the RFC 6598 Shared Address Space (100. 64. 0. 0/10), allowing attackers who can supply arbitrary URLs to potentially access internal services hosted in this range. This is particularly relevant in environments like AWS EKS where this CIDR is commonly used for internal pod networking. The vulnerability affects versions of requests-hardened prior to 1. 2. 1 and has a medium severity rating with a CVSS score of 6. 5.
AI Analysis
Technical Summary
The requests-hardened library, which enhances the Python requests library with additional security features, had an SSRF protection bypass for IP addresses in the RFC 6598 Shared Address Space (100.64.0.0/10). This allowed attackers able to provide arbitrary URLs to bypass SSRF protections and access internal services within this IP range. This issue is environment-dependent and mainly affects deployments using the 100.64.0.0/10 CIDR for internal networking, such as AWS EKS clusters. The vulnerability is tracked as CVE-2026-42175 and is fixed in requests-hardened version 1.2.1 and later.
Potential Impact
Successful exploitation allows an attacker to bypass SSRF protections and access internal services hosted within the 100.64.0.0/10 IP range. The impact depends on the deployment environment; environments using this CIDR for internal networking are exposed to potential unauthorized internal network access. Confidentiality can be compromised (high impact), integrity impact is low, and availability is not affected.
Mitigation Recommendations
A patch is available in requests-hardened version 1.2.1 and later that fixes this SSRF bypass issue. Since this is a cloud service, the vendor typically manages remediation server-side. Users should ensure they are running the patched version or verify with the vendor that the service has been updated. Patch status is confirmed as available. No additional mitigation steps are indicated by the vendor advisory.
