CVE-2026-63307 Details
Description
Chat2DB before 5.3.0 contains an insecure direct object reference vulnerability in the GET /api/connection/datasource/{id} endpoint. The handler calls dataSourceService.queryExistent(id, ...) without an ownership check and returns the decrypted password field, allowing any authenticated non-admin user to enumerate datasource IDs and read the plaintext database credentials of datasources owned by other users.
A vulnerability allowing insecure direct object reference has been identified in Chat2DB versions prior to 5.3.0. This vulnerability exists in the GET /api/connection/datasource/{id} endpoint, where the absence of an ownership check allows authenticated non-admin users to access decrypted database passwords for datasources owned by other users. The issue arises because the endpoint's handler calls dataSourceService.queryExistent(id, ...) without verifying ownership, enabling users to enumerate datasource IDs and retrieve plaintext database credentials.
Users can upgrade to Chat2DB version 5.3.0 or later, where this vulnerability has been addressed.
