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.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
