Summary An authenticated user with base-create permission can attach a SQLite source pointing at an arbitrary file on the NocoDB host, including NocoDB's own internal databases. Details The SQLite client and the base/integration create services accepted a caller-supplied filename and passed it to "fs.exists" and "fs.open('w')" without restricting the location. A user could point a source at "noco.db", at a tenant database under "nc_minimal_dbs/", or at any writable path the NocoDB process can reach, and then read or overwrite its contents through the regular table APIs. Impact Disclosure and modification of NocoDB internal state, of other tenants' databases, and of any file the NocoDB process can read or write. Authentication and base-create permission are required.
