free-fs 2.0.1 through 2.3.1 contains an SQL injection vulnerability in FileShareServiceImpl.getPages, which passes the orderBy parameter of the /apis/share/pages endpoint verbatim into the ORDER BY clause via MyBatis-Flex without a column whitelist. Authenticated users can supply CASE WHEN subquery expressions that use share ordering as a boolean oracle to read arbitrary database contents, such as share codes.
CWE-89
