Flextype CMS versions up to v1.0.0-dev have an expression language injection vulnerability. Authenticated attackers with a valid API token can exploit this flaw via the POST /api/v1/query endpoint to read arbitrary files on the server. The vulnerability arises from unsanitized user input passed to the Symfony ExpressionLanguage engine, allowing access to application objects like filesystem() and serializers(). This can lead to conditional remote code execution if an attacker can place a PHP file on the server through another method.
