CVE-2026-41170 WRITEUP HIGH WRITEUP
Squidex has SSRF via Backup Restore Endpoint — Admin-Controlled URL Download Allows Internal and External Requests
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.
CVE-2026-41171 WRITEUP HIGH WRITEUP
SSRF via Jint Scripting Engine HTTP Functions Due to Missing SSRF Protection on "Jint" HttpClient
Squidex is an open source headless content management system and content management hub. Versions prior to 7.23.0 have a Server-Side Request Forgery (SSRF) vulnerability due to missing SSRF protection on the `Jint` HTTP client used by scripting engine functions (`getJSON`, `request`, etc.). An authenticated user with low privileges (e.g., schema editing permissions) can force the server to make arbitrary outbound HTTP requests to attacker-controlled or internal endpoints. This allows access to internal services and cloud metadata endpoints (e.g., IMDS), potentially leading to credential exposure and lateral movement. Version 7.23.0 contains a fix.
CVE-2026-41172 WRITEUP HIGH WRITEUP
Squidex vulnerable to Server-Side Request Forgery (SSRF) via URL-based asset upload (/api/apps/{app}/assets)
Squidex is an open source headless content management system and content management hub. Prior to version 7.23.0, an SSRF vulnerability allows a user with asset upload permission to force the server to fetch arbitrary URLs, including localhost/private network targets, and persist the response as an asset. Version 7.23.0 contains a fix.
CVE-2026-41177 WRITEUP MEDIUM WRITEUP
Squidex has Blind SSRF via file:// Protocol in Restore API leading to Local File Interaction
Squidex is an open source headless content management system and content management hub. Prior to version 7.23.0, the Squidex Restore API is vulnerable to Blind Server-Side Request Forgery (SSRF). The application fails to validate the URI scheme of the user-supplied `Url` parameter, allowing the use of the `file://` protocol. This allows an authenticated administrator to force the backend server to interact with the local filesystem, which can lead to Local File Interaction (LFI) and potential disclosure of sensitive system information through side-channel analysis of internal logs. Version 7.23.0 contains a fix.
