typo3/cms-core is vulnerable to Information Disclosure. The vulnerability exists because calling an URI with page-id query parameters that are not part of a particular site is not properly restricted which allows an attacker to add crafted query parameters to the URL of publicly available sites and access the content of an internal site.
