QID 996547: PHP (Composer) Security Update for flarum/core (GHSA-733r-8xcp-w9mr)

Sample: example.com/logout?return=https://google.com. For logged-in users, the logout must be confirmed. Guests are immediately redirected. This could be used by spammers to redirect to a web address using a trusted domain of a running Flarum installation.

Successful exploitation of this vulnerability could lead to a security breach or could affect integrity, availability, and confidentiality.
