Description

DataEase is an open source data visualization and analysis tool. Versions prior to 2.10.23 have a path traversal vulnerability. The root cause is that on Windows, the `FILE_SEPARATOR` is `\`, while the server only filters the `/` character during string truncation. The vulnerability has been fixed in v2.10.23.
