Summary TYPO3 vulnerable to Weak Authentication in Session Handling > ### CVSS: `CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:N/E:X/RL:O/RC:C` (4.0) ### Problem Given that there are at least two different sites in the same TYPO3 installation - for instance _first.example.org_ and _second.example.com_ - then a session cookie generated for the first site can be reused on the second site without requiring additional authentication. This vulnerability primarily affects the frontend of the website.
