CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:L/A:L/E:F/RL:O/RC:C(5.3)
Problem
Due to the lack of handling user-submitted YAML placeholder expressions in the site configuration backend module, attackers could expose sensitive internal information, such as system configuration or HTTP request messages of other website visitors.
A valid backend user account having administrator privileges is needed to exploit this vulnerability.
Solution
Update to TYPO3 versions 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1 that fix the problem described above.
Credits
