Campaign Configuration Authorization Automation: The App Said No; the Database Never Heard It

A settings screen that correctly checks a specific permission before allowing a save is doing exactly the right thing at exactly the layer it operates in — the interface itself. But an interface is only ever one PATH to the underlying data, and a rule enforced solely at that one path protects against every request that happens to go through it, while leaving completely open any request that reaches the same table by a different path. A rule that is genuinely meant to hold has to be enforced at the layer that is actually common to every possible path — the database itself — or it is, in a very real sense, not actually a rule about the DATA at all, only a rule about one particular DOORWAY into it.

Centriu Loop's own settings interface already correctly declared, and enforced at that layer, that a sales-role account could not configure the organization's own cashback rate — the application's own permission model explicitly marks that capability as unavailable to that role, and the settings screen checks it before allowing a save.

The database tables actually holding this configuration — one recording individual marketing campaigns, each with its own cashback percentage, and one holding an organization's own overall default settings — carried no equivalent role check of their own. Two compounding gaps produced this: first, the underlying database platform's own automatic default privileges had granted broad INSERT and UPDATE access to both tables the moment they were created, and an earlier hardening pass had revoked DELETE and TRUNCATE from them but stopped there, never reaching INSERT or UPDATE; second, the only additional access rule either table actually had checked solely whether a caller belonged to the correct organization, with no further distinction for which specific role that caller held within it.

Measured directly against a real database running the live production schema, with a genuine positive control built into the same test: an account from a DIFFERENT organization was correctly refused on every attempt, exactly as intended — but a sales-role account from the SAME organization could insert a brand-new campaign at an arbitrary rate, or directly overwrite the organization's own stored default rate, with no error returned at all. Testing only the cross-organization scenario, on its own, would have reported this configuration as completely secure.

The fix closes both layers at once, in a single migration applied alone to production and verified beforehand with a dry run confirming exactly one migration would be selected. The broad default INSERT and UPDATE privileges are revoked outright from both tables, and the write-permitting policies that had relied solely on organization membership are removed entirely. Configuring a campaign's own rate, or an organization's own default, is now only reachable through the platform's own trusted backend connection — precisely the same path the application's properly permission-checked settings interface was already using. The fix's own account is explicit that this does NOT mean copying the ledger's own append-only treatment onto these tables: a campaign and a default rate are, by design, records meant to be edited by whoever legitimately holds the right role — the actual defect here was always about WHO could write to them, never about whether writing itself should remain possible at all.

Before the fix, a settings screen correctly displayed no option for a sales-role account to change the cashback rate — the interface's own sign on the door said no. But the door itself, reached directly rather than through that interface, had no lock enforcing the same rule: the identical account could insert a new campaign at any rate it chose. After the fix, the door itself refuses that same account, regardless of which path is used to reach it.

Centriu Loop's campaign and organization-settings configuration can now only be written through the platform's own trusted backend path, closing a gap where the application's interface correctly restricted a sales-role account from configuring the cashback rate while the underlying database enforced no equivalent rule — allowing the identical account to reach the same outcome by writing directly to the table.

This automation covers specifically the role-based write authorization for Centriu Loop's own campaign and organization-settings configuration. It is a distinct mechanism from this pillar's separate pages on the cashback ledger's own append-only enforcement — those cover a genuinely different kind of record (a permanent financial history) that is deliberately NOT meant to be editable by anyone at all after the fact, unlike a campaign or a default rate, which is meant to remain editable by the right role.

Relying on an application's own interface to enforce a role-based restriction is straightforward to build and works correctly for as long as every request genuinely goes through that one interface — a completely reasonable assumption until it isn't. Enforcing the identical rule at the database layer itself, by narrowing default privileges and requiring a role check rather than membership alone, is the only version of the two that holds regardless of which path a request actually takes to reach the data — and it is the specific gap testing only a cross-organization scenario would never have revealed on its own.
