CVE-2026-63307

Full vulnerability record from the local CVENow database.

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.
