Technical summary

The vulnerability is caused by a lack of ownership checks in the dataSourceService.queryExistent function. This function is called by the GET /api/connection/datasource/{id} endpoint, which returns the decrypted password field for the specified datasource ID. As a result, an authenticated non-admin user can enumerate datasource IDs and read the plaintext database credentials of datasources owned by other users. The affected product is Chat2DB, and the vulnerability is fixed in version 5.3.0 or later.

Defensive priority
