Vulnerability Advisory : SSRF via Jint Scripting Engine HTTP Functions Due to Missing SSRF Protection on "Jint" HttpClient with LOW Attack Complexity

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.
