User session identifiers were stored in cleartext - without processing of additional cryptographic hashing algorithms. This vulnerability cannot be exploited directly and occurs in combination with a chained attack - like for instance SQL injection in any other component of the system. Solution Update to TYPO3 versions 9.5.23 or 10.4.10 that fix the problem described.
