CVE-2026-41170
Received Received - Intake
Authenticated SSRF in Squidex RestoreController Enables Internal Access

Publication date: 2026-04-22

Last updated on: 2026-04-23

Assigner: GitHub, Inc.

Description
Squidex is an open source headless content management system and content management hub. Prior to version 7.23.0, the `RestoreController.PostRestoreJob` endpoint allows an administrator to supply an arbitrary URL for downloading backup archives. This URL is fetched using the "Backup" `HttpClient` without any SSRF protection. A malicious or compromised admin can use this endpoint to probe internal network services, access cloud metadata endpoints, or perform internal reconnaissance. The vulnerability is authenticated (Admin-only) but highly impactful, allowing potential access to sensitive internal resources. Version 7.23.0 contains a fix.

Executive Summary

This vulnerability exists in Squidex, an open source headless content management system, prior to version 7.23.0. The issue is in the RestoreController.PostRestoreJob endpoint, which allows an administrator to provide an arbitrary URL to download backup archives. The URL is fetched using the Backup HttpClient without any Server-Side Request Forgery (SSRF) protection.

Because of this, a malicious or compromised administrator can exploit this endpoint to probe internal network services, access cloud metadata endpoints, or perform internal reconnaissance within the system.

The vulnerability requires administrator authentication but is highly impactful due to the potential access it grants to sensitive internal resources. The issue was fixed in version 7.23.0.

Impact Analysis

This vulnerability can have significant impacts if exploited. A malicious or compromised administrator can use it to access sensitive internal resources by probing internal network services or accessing cloud metadata endpoints.

Such access could lead to unauthorized internal reconnaissance, potentially exposing confidential information or enabling further attacks within the internal network.

Mitigation Strategies

To mitigate this vulnerability, upgrade Squidex to version 7.23.0 or later, which contains the fix for this issue.

Since the vulnerability allows an authenticated administrator to supply arbitrary URLs for backup downloads without SSRF protection, restricting administrative access and monitoring admin activities can also help reduce risk until the upgrade is applied.

Compliance Impact

The vulnerability allows an authenticated administrator to supply arbitrary URLs for downloading backup archives without SSRF protection, potentially enabling access to sensitive internal resources and internal network services.

Such unauthorized access to internal resources could lead to exposure of sensitive data, which may impact compliance with data protection standards and regulations like GDPR and HIPAA that require safeguarding sensitive information.

However, the provided information does not explicitly describe the direct effects on compliance with these standards.
