December 25, 2023 (updated January 3, 2024)

In TYPO3 11.5.24, the filelist component allows attackers (who have access to the administrator panel) to read arbitrary files via directory traversal in the baseuri field, as demonstrated by POST /typo3/record/edit with ../../../ in data[sys_file_storage]*[data][sDEF][lDEF][basePath][vDEF].
