CVE-2026-41171

SSRF via Jint Scripting Engine HTTP Functions Due to Missing SSRF Protection on "Jint" HttpClient

Published Apr 22, 2026 CVSS 4.0 · 7.3 High EPSS < 1% KEV · Not listed

Description

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.

Analysis

Technical impact

Squidex versions before 7.23.0 allow an authenticated user with low privileges, such as schema editors, to direct the server’s Jint HTTP client to make arbitrary outbound HTTP requests. The missing SSRF protection enables the attacker to reach internal or cloud metadata services, potentially exposing credentials and providing a foothold for lateral movement. This flaw is identified as CWE‑918 (Server‑Side Request Forgery).

Affected Systems

The vulnerability affects the Squidex content management platform, specifically all releases earlier than 7.23.0. Users running those earlier versions are at risk if they continue to provide authenticated access with editing permissions.

Risk and Exploitability

The CVSS score of 7.3 indicates a high severity risk. EPSS data is not available, and the issue is not listed in CISA’s KEV catalogue, suggesting no publicly known exploits yet. However, the attack requires only a low‑privileged authenticated session and can be used to reach internal endpoints, so the real‑world risk remains significant, especially in environments with exposed internal services or cloud metadata access. The attack vector is likely external, mediated by legitimate API calls from a compromised or malicious user account.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

OpenCVE Recommended Actions

Upgrade Squidex to version 7.23.0 or later to apply the SSRF fix.
If an immediate upgrade is not feasible, remove or reduce the editing permissions of users who can execute scripts or disable the Jint scripting engine functions entirely.
Implement outbound firewall or proxy restrictions to limit the Squidex server’s ability to reach internal network addresses or cloud metadata endpoints.
