Why

RAPSController had Policy = "2faAuthentication" commented out while every RAPS API controller required it. A user without a Duo credential got the pages and nav rendered normally, then a 403 from every call behind them. The frontend rewrites 403s to a generic permission message, so the real reason never surfaced.

That is one instance of a pattern, and this PR fixes the others alongside it: places where the UI offers something the API then refuses, and places where the API is looser than the page in front of it.

What changed

Authorization. Re-enabled the 2FA policy on RAPSController. MembersController.Search and Get had no authorization at all, so GET /raps/VIPER/Members?search= was reachable unauthenticated and returned identities and email addresses; attribute-routed controllers are not covered by the RequireAuthorization() on the conventional routes. They now require the RAPS role plus the union of the permissions behind the three pages that use them. AuditController was missing the 2FA gate its peers have.

Dead-end links. The Role List nav item was added unconditionally while its action returned a 403 view, and CanViewRoleList counted delegated roles across every instance, so a delegate whose roles live in one instance was offered the list in the others and landed on nothing. Both now use the same instance-scoped check the page uses. In the Directory, the card view showed the emulate button to everyone while the table view checked SVMSecure.SU, and the table view's link used a bare /EmulateUser/ that escapes the /2 PathBase.

Permission cache. Invalidation lived at each call site and several write paths never called it: the nightly role refresh, the OU group sync, and role CRUD all changed membership without evicting, and entries never expired, so a revoked permission kept working until the app pool recycled. Invalidation now lives in a SaveChanges interceptor on RAPSContext, covering any path that reaches the database including ones added later, and expanding a role-level change to that role's members. There is deliberately no TTL: with invalidation complete it would only decide how long a missed eviction goes unnoticed, and VIPER 1 does not cache at all. The cache also now keys on MothraId rather than the nullable LoginId, which collided across every user without one.

Performance. GetAppRolesForUser runs a two-Include query and Nav() reached it once per instance on every page load. It is now memoized per request.

The first commit is separate and reviewable on its own: it serializes the test classes that share the process-wide HttpHelper.Cache, which xUnit was running in parallel.

Verified

Against a running instance: granting a permission moved the target's effective set from 138 to 139 immediately and revoking moved it back, with no logout and no wait. A RAPS Users member with no RAPS permissions now gets 403 from the member endpoints while an admin still gets results. A non-admin no longer sees the Role List link that used to 403, and a delegate sees it only in the instance holding their roles.

Before TEST

This locks out anyone without a Duo credential instead of showing them a broken UI, so RAPS users should hear about it first. If someone still cannot get in, they need to end the CAS SSO session, not just the VIPER session: credentialType is captured once at CAS login and a silent SSO re-auth returns the original value.

Found, not fixed here

MembersController is the only RAPS API controller deriving from ControllerBase instead of ApiController, so it misses [ApiResponse], [ApiExceptionFilter], and [ApiSessionUpdateFilter]: it returns bare arrays where every sibling returns the { success, result } envelope, its exceptions skip the standard error shape and correlation id, and calls to it do not refresh the session timeout. Three cshtml pages consume the bare arrays, so correcting it is an API contract change.

Program.cs has no FallbackPolicy, which is what let MembersController drift. Adding one is not a drop-in: CMSController enforces per-file permissions itself and serves public files, LayoutController returns a permission-filtered nav anonymously, and LoggedInUserController answers anonymously by design. Each needs auditing and [AllowAnonymous] first.

Smoke test

SMOKETEST-RAPS-Authorization.md. Everything except the Duo sections was run locally. Those belong on TEST because Development deliberately bypasses Duo, since no Duo credential can be issued for a localhost callback. The policy itself is guarded by RapsControllerAuthorizationTests, which asserts every RAPS controller carries it and runs in every environment.

📝 Walkthrough

Walkthrough

The change secures RAPS controllers and role-list access, restricts SVM emulation links, keys permission caches by Mothra ID, and invalidates affected caches after RAPS writes.

Changes

Security and cache behavior

Layer / File(s) Summary
Permission cache lifecycle
web/Classes/UserHelper.cs, test/Classes/UserHelperCacheTests.cs, test/HttpHelperCacheCollection.cs, test/ClinicalScheduler/..., test/Effort/...
User permission caches use Mothra ID key helpers. Cache clearing removes both deny variants. Tests validate user-specific invalidation and coordinate access to the process-wide cache.
RAPS cache invalidation
web/Areas/RAPS/Services/RapsCacheInvalidationInterceptor.cs, web/Program.cs, test/RAPS/RapsCacheInvalidationInterceptorTests.cs
The EF Core interceptor tracks affected RAPS members and roles during saves, then clears cached roles and permissions after committed changes. RAPS context registration installs the interceptor.
RAPS authorization and role-list access
web/Areas/RAPS/Controllers/..., web/Areas/RAPS/Services/RAPSSecurityService.cs, test/RAPS/RapsControllerAuthorizationTests.cs, test/RAPS/RapsSecurityServiceTests.cs
RAPS controllers require application roles and the 2faAuthentication policy. Role-list access uses CanViewRoleList, with support for instance permissions and delegated roles. Tests cover controller attributes and role-list rules.
Directory emulation authorization
web/Areas/Directory/Views/Card.cshtml, web/Areas/Directory/Views/Table.cshtml
The SVM emulation link requires SVMSecure.SU. The emulation URL uses HttpHelper.GetRootURL().

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 79461

The PR improves authorization and permission-cache invalidation, but revoked permissions can still remain active on other application instances, creating a bounded security risk in multi-instance deployments; this requires explicit owner acceptance or follow-up before merge.

Pull request overview

This PR tightens RAPS/Directory authorization to prevent “page renders but API 403s” failures (notably enforcing Duo 2FA), closes unauthenticated access gaps on RAPS endpoints, and makes RAPS permission caching correct by moving invalidation into an EF Core SaveChanges interceptor.

Changes:

  • Re-enabled Duo 2FA gating on RAPS controllers and added missing authorization/permission gates to previously unauthenticated RAPS API endpoints.
  • Centralized RAPS permission-cache eviction via an EF Core SaveChangesInterceptor, and changed cache keys to use MothraId to avoid collisions.
  • Fixed UX dead-ends (instance-scoped Role List visibility; Directory emulate affordances and PathBase-safe emulate links) and memoized per-request role lookups.

  • The role-expansion query uses a potentially-large in-memory collection in .Contains(). On SQL Server this can hit parameter-count limits / generate inefficient SQL. Elsewhere in the codebase large Contains lists are wrapped with EF.Parameter(...) to force OPENJSON translation (SQL Server 2016 compat level 130).

  • In Get(), VwAaudUser is queried without including or projecting TblRoleMembers/TblMemberPermissions, but those navigations are initialized to empty lists (VwAaudUser.cs). That means CountRoles/CountPermissions here will always return 0 (or otherwise be stale), unlike Search() which includes them.
        [Permission(Allow = "RAPS.Admin,RAPS.UserLookup,RAPS.EditRoleMembership,RAPS.EditMemberPermissions")]
        [HttpGet("{memberId}")]
        public async Task<ActionResult<MemberSearchResult>> Get(string memberId)
        {
            var member = await _context.VwAaudUser.FirstOrDefaultAsync(u => u.MothraId == memberId);

  • The filter .Where(r => r.TblRoleMembers.Any(...)) translates to a correlated EXISTS subquery. This repo’s EF guidance is to avoid .Any() inside .Where() on large tables; using an IN (subquery) via a role-id set (or a join) is typically easier for SQL Server to optimize and avoids correlated execution plans.

                        .ThenInclude(cr => cr.Role)
                    .Where(r => r.Application == 1)
                    .Where(r => r.TblRoleMembers.Any(rm => rm.MemberId == userId))

…ache

HttpHelper.Cache is a process-wide static, and xUnit runs each test class
as its own collection in parallel. Classes that call HttpHelper.Configure
could swap the cache out from under each other mid-test, so a test could
seed one instance and assert against another.

- IntegrationTestBase configures the cache for every subclass, so two
  classes were racing without referencing TestDataBuilder themselves
…dpoints

RAPSController had the 2FA policy commented out while every RAPS API
controller required it, so the pages and nav rendered for a user without a
Duo credential and every call behind them returned 403. The frontend
rewrites 403s to a generic message, so the real reason never surfaced.

- MembersController Search and Get had no authorization at all: attribute
  routes are not covered by RequireAuthorization on the conventional routes.
  They now also need one of the permissions behind the pages that use them,
  which the RAPS role alone did not imply
- Gate the Role List nav item on the rule its action enforces, scoped to the
  requested instance so a delegate is not sent to a list filtered to nothing
- Show the Directory emulate button only with SVMSecure.SU, matching the
  table view, and keep the app base on its link
- Memoize the delegate-role lookup, which Nav queried once per instance
Invalidation lived at each call site and several write paths never called
it: the nightly role refresh (RoleViews via RapsRoleRefreshScheduledJob),
the OU group sync, and role CRUD all changed membership without evicting.
Entries never expired either, so a revoked permission kept working until
the app pool recycled.

- Move invalidation into a SaveChanges interceptor on RAPSContext so any
  path reaching the database is covered, including ones added later
- Expand a role-level permission change to that role's current members
- Key the cache on MothraId, not the nullable LoginId, which collided
  across every user without one and is what the RAPS tables key on anyway
The Development bypass succeeded the requirement and then still stored the
"two-factor authentication is required" message, which was never surfaced
but is misleading to anyone inspecting HttpContext.Items locally.

- Add coverage pinning the bypass, so it is not mistaken for an oversight
  and removed: no Duo credential can be issued for a localhost callback
