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.
