Sažetak

CloudBeaver through 25.3.5 contains a missing authorization vulnerability in WebSQLResultServlet that allows any web session holder to read other users' LOB export files from a shared folder. Attackers can guess table and column names and enumerate second-resolution timestamps to download victims' LOB values, including data from connections they cannot query.
