CVE-2024-24552: Bludit is Vulnerable to Session Fixation

See OWASP Session Management Cheatsheet: The session ID must be renewed or regenerated by the web application after any privilege level change within the associated user session. The most common scenario where the session ID regeneration is mandatory is during the authentication process, as the privilege level of the user changes from the unauthenticated (or anonymous) state to the authenticated state though in some cases still not yet the authorized state. Common scenarios to consider include; password changes, permission changes, or switching from a regular user role to an administrator role within the web application. For all sensitive pages of the web application, any previous session IDs must be ignored, only the current session ID must be assigned to every new request received for the protected resource, and the old or previous session ID must be destroyed.
