fix(security): break-glass repair of a genuinely unreachable knowledge fact or envelope secret, through each type's own service (#15779, #16940) - #16927
Conversation
…sources (#15779) is_visible() has no admin bypass, so a resource with owner_id=None, no grant, and a scope whose own key is also null (ORGANIZATION with company_id=None, GROUP with no group_ids, or any of USER/PRIVATE/SESSION/SHARED/WORKFLOW) is denied to every principal including an admin -- and the repair (assign owner, add a grant) is gated by the same check that is denying, with no in-app path out. - autobot_shared/scoping/visibility.py: is_unreachable(resource, has_grant) mirrors is_visible()'s fall-through for "any principal" rather than one -- a pure predicate, tested against synthetic ResourceDescriptors, since no concrete resource table today has this shape live (secrets.owner_id is NOT NULL at the DB level; knowledge_facts has no scope/company_id at all). - services/resource_visibility.py: repair_grant() grants access via the already-generic resource_grants table rather than mutating the resource's own owner/scope columns, which this module has no write path to -- a grant is the one repair every resource type already honors unconditionally, ahead of any scope rule. Admin-only by trust boundary (same as every other service function reached only through an admin-gated route); every call audited via services.audit_logger.audit_log. - api/admin_resource_grants.py: POST /admin/resource-grants/repair, gated by auth_rbac.require_role("admin", "superadmin"). - services/resource_grant_store.py: grant()/revoke() now invalidate resource_visibility's cache themselves (deferred import to avoid the circular import), so a repair is visible with no restart -- previously every caller had to remember to call invalidate() itself.

Merge Risk: 🟡 Moderate · up to The new administrator break-glass repair feature is likely broken for knowledge facts: the knowledge-store connection is created incorrectly, so listing or repairing unreachable facts would fail at runtime. Secret repair can also be refused in cases it is meant to fix, and repair audit records may not identify the operator uniquely. Existing functionality is largely unaffected, but these should be resolved before merging so the new recovery workflow actually works. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

of resource.owner_id rather than checking only for None, while preserving the
has_grant condition, so an empty owner ID matches is_visible() behavior.
In `@autobot-backend/services/resource_grant_store.py`:
- Line 50: Move visibility-cache invalidation in grant() and revoke() from
pre-commit execution to queued callbacks that run only after a successful
transaction commit, and discard those callbacks on rollback. In
resource_grant_store_test.py at lines 70-71 and 84-85, add coverage for commit
and rollback behavior. In resource_visibility_test.py at lines 56-69, perform
visibility checks through a separate session after commit so the tests validate
committed cache invalidation.
- Around line 16-26: Extend the visibility-cache invalidation flow around
_invalidate_visibility_cache, grant(), revoke(), and
resource_visibility.invalidate() to propagate invalidation across workers via
the repository’s existing Redis pub/sub mechanism. Publish the resource key only

currently unreachable.
- Around line 79-89: Move the success audit emission in the resource repair

Propagate visibility-cache invalidation across API workers.
POST /api/admin/resource-grants/repair reaches resource_grant_store.grant(), and revoke() is another reachable grant mutation. Both call _invalidate_visibility_cache(), which invokes resource_visibility.invalidate() and removes only the current process's entry from the module-level _cache.
The production configuration supports four backend workers and multi-replica backend deployments using PostgreSQL. After one worker grants or revokes a row, another worker can retain its cached decision. can_access() returns that decision before querying has_grant(). It can therefore deny a new grant or continue to allow access after a revoke when the explicit grant was the only positive condition.
Use a cross-worker invalidation mechanism, such as the repository's Redis pub/sub pattern. Publish the resource key after the database change commits, and have every API worker call its local invalidate() when it receives the event.

Defer visibility-cache invalidation until the database transaction commits.
flush() does not commit. A concurrent request can cache the old committed decision after the early invalidation, and no later invalidation runs after commit. After a revoke, the cache can therefore continue to allow access.
Queue invalidation for successful commits in grant() and revoke(), discard queued invalidations on rollback, and add commit and rollback tests. The visibility tests must query through a separate session after commit.

Restrict repair grants to existing unreachable resources.
The admin endpoint is documented as a break-glass repair for an unreachable resource, but it forwards the caller-supplied resource_type and resource_id directly to store.grant(). That function creates or updates a generic grant without resolving the concrete resource. The endpoint can therefore create grants for non-existent resources or grant access to resources that are already reachable.
Add a trusted resource-type lookup, reject unknown or non-existent targets, and call is_unreachable() before store.grant(). The current code has no such lookup, and the tests cover only the intended unreachable-resource case.

Emit the success audit event after the grant commits.
store.grant() only flushes the ResourceGrant. The request dependency commits the session after the route returns, but audit_log() queues the success event independently for Redis or file storage. If that commit later fails and rolls back, resource.repair_grant can remain recorded as successful without a grant.
Register the audit call with the existing post-commit hook, or persist both operations through a transactional outbox. Do not emit result="success" before the SQL commit.

| A resource with owner_id=None, no resource_grants row, and a scope whose own key is also null (ORGANIZATION with company_id=None, GROUP with no group_ids, or any of USER/PRIVATE/SESSION/SHARED/WORKFLOW) was denied to every principal including an admin, with no in-app remedy: the repair itself was gated by the same check that denied it. Added a pure `is_unreachable()` predicate for detecting this orphan state, an admin-only, audited `repair_grant()` break-glass path (exposed via `POST /admin/resource-grants/repair`) that grants access without needing to touch the resource's own owner/scope columns, and made `resource_grant_store.grant()`/`revoke()` invalidate the visibility cache automatically instead of relying on every caller to remember to. |

Document the /api prefix for the repair endpoint.
admin_resource_grants.py defines POST /resource-grants/repair on a router with the /admin prefix. The core router registry includes it, and app_factory.py mounts registered routers under /api.

Blocked — security defect, not a nitpick. Confirmed Concrete failure scenario: an admin (or anyone who obtains an admin session — exactly the scenario a break-glass audit trail exists to catch) calls This means the mechanism reviewed and billed as a narrowly-scoped "break-glass repair for unreachable resources" is, in the actual code, a general-purpose "any admin can grant any user access to any named resource" endpoint — materially broader than issue #15779 asked for, with an audit trail that can't tell the two cases apart after the fact. What IS solid, confirmed independently: Fix needed before this can close #15779: before Issue #15779's AC2 ("scoped to repair operations") and AC4 ("an orphan-detection query exists... so orphans surface") are each only partially met as a result — flagging so the issue isn't closed by this PR as-is. |
…nly a genuine one (#15779, #16927, #16940) Review of #16927: repair_grant() granted unconditionally, and is_unreachable() had no caller. Worse, the grant it wrote went to resource_grants, which no production access check reads -- secrets are gated by envelope vault grants, knowledge facts by KnowledgeOwnership.check_access with its own shared_with -- so the break-glass repaired nothing. Owner ruling on #16927: repair each type through its own service and grant source. - services/orphan_repair.py: the break-glass. A repair is refused unless the resource is genuinely unreachable -- no live owner, no grant a live principal holds, a scope key nobody holds -- and the new owner must be a proven live user. Every attempt is audited with the conditions it was judged on: repaired ("success"), refused ("denied") or failed ("error"), so a failed break-glass is no longer invisible (#16940). - services/orphan_repair_types.py: knowledge_fact, judged exactly as check_access reads the metadata and repaired via KnowledgeBase.update_fact (which re-files the ownership indexes); secret = envelope secret, orphaned when every grant names a vault no live principal holds, repaired by EnvelopeSecretsService.share() to the new owner's user vault -- the data key is re-wrapped, the value never decrypted, returned or logged. - "Live" is proven, never assumed: a deleted user (no row, or deleted_at set) is dead; a deactivated one is live; an id that is not a UUID, or a non-user vault, cannot be proven dead and so blocks the repair. - is_unreachable() takes a required owner_is_live, covering a deleted user's leftover owner id (#15779's own case), and checks ownership by truthiness as is_visible() does. Secret.is_accessible_by no longer turns a null owner into the truthy "None". - Admin routes: GET /api/admin/orphans (#15779 AC4) and POST /api/admin/orphans/repair (409 on a reachable resource). The resource_grants repair route, repair_grant() and its tests are removed: that write path reached no access check. Tests: the knowledge repair is proven through the real check_access; the envelope repair end to end in the migration gate (the new owner reads the secret through their vault, and the plaintext appears in neither result nor audit); negative controls for every "reachable" shape.

Use a stable actor identity for development-header repairs.
require_role("admin", "superadmin") admits an admin development-header principal, but resolve_principal_id() returns None because it has no user identity. Line 67 then records a role-based username such as dev_admin, which can merge different operators under one audit actor. Reject principals without a stable identifier, or provide a stable identifier for each non-user principal.

Supply the required application argument to the knowledge-base factory.
get_or_create_knowledge_base requires an app argument. The default KnowledgeFactRepairer calls it without one. Every production knowledge-fact list, assessment, and repair therefore raises TypeError.
Inject an application-bound kb_factory, or change this integration to use a valid no-argument factory.

Do not use owner_id as envelope-secret reachability. EnvelopeSecretRepairer._judge() passes secret.owner_id to owner_blocks_repair(), which returns True for a live user based only on user_state(). EnvelopeSecretsService.read() authorises access only through a matching SecretGrant. A live owner_id can therefore suppress repair when no live grant exists. Base the assessment on live vault grants, not on owner_id.

…structions rule (#17028) CLAUDE.md is an index; the global "one line per rule, >2 lines goes to a referenced doc" rule applies. Moves the 8-item checklist to CLAUDE_REVIEW.md as author-facing self-review guidance, leaves one table row in CLAUDE.md, and condenses item 3 to point at the existing "No hardcoded UI strings" rule instead of restating it. Citations spot-checked against the actual PR review comments (#16973, #16927) before push, per review from autobot-ai-66.
… branch (#16665, #16908) #16716 and #16918 (issue #16908) both edited knowledge_ai_stack.py's search helpers -- per the repo's same-file-overlap rule, they land as one PR. This carries #16908's four duplicate-route fixes onto #16716's already-pushed security fix. Carried from #16918: - api/admin_schedulers.py deleted entirely (GET /admin/schedulers always lost to the operator-override-respecting services.scheduler_toggles sibling). - api/self_capabilities.py re-mounted at /self (was "", colliding with api/chat.py's own /capabilities). - api/knowledge_ai_stack.py's /stats re-pathed to /ai-stack/stats (was colliding with api/knowledge.py's /stats). - api/knowledge_ai_stack.py's dead POST /search handler and its helpers (_search_local_knowledge_base, _search_rag, _search_librarian, _combine_search_results, _run_all_search_sources) deleted -- always shadowed by api/knowledge_search.py's own POST /search, which already carries real tenant filtering (#15745). - Matching test/registration updates in core_routers.py, feature_routers.py, self_capabilities_integration_test.py, api_endpoint_migrations_test.py. Kept from #16716: rag_search()'s is_admin= bypass removal (the tenant-scoping fix) survives untouched -- it is not one of the deleted functions. kb_read_visibility_allowlist.py / kb_read_visibility_guard_test.py: re-scanned against the fully merged tree (not either PR's own stale number). UNFILTERED_READ_CEILING 92 -> 94 -- entirely from origin/main's own #16927 orphan-repair feature picked up by this merge (two admin-gated KnowledgeFactRepairer reads, classified ADMIN_ONLY), not from #16908 or #16716 themselves (deleting the already-filtered _search_local_knowledge_base changes nothing the scan counts). Also fixed, discovered while consolidating (both pre-existing on this branch, unrelated to #16716/#16908's own diffs): - api/ai_stack_integration.py's grandfathered file-size ceiling was stale at 638 after #16716's own chat()/rag_query() filtering fix grew it to 667 lines without updating the ratchet -- re-frozen at the true current size. - Two pre-existing stray-indentation typos in the ratchet baseline dicts (feature_routers.py, network_constants.py entries) that predate this session, fixed in passing since both files were already being edited here.

Thinking Path
The first version of this PR repaired an "orphan" by writing a
resource_grantsrow. Review found two defects in that: the repair granted unconditionally (a reachable resource could be taken), and no access check readsresource_grants— the only reader,resource_visibility.can_access, has no production caller. The grant row changed nothing a user could observe.The owner ruled option (b): a repair goes through each resource type's own service and writes that type's own owner, judged by that type's own access gate. An unknown type is refused. A repair needs all three to hold: no live owner (null, or an id proven to be a deleted user), no grant held by a live principal in the type's own grant source, and a scope key nobody holds. "Live" is proven, never assumed: an id that does not resolve to a user row (a non-UUID such as
admin) and every non-user vault count as live and block the repair. The new owner must be proven live.Two types have a real access gate and a real way to be orphaned:
knowledge_factKnowledgeOwnership.check_accessSHAREDvisibility +shared_withKnowledgeBase.update_fact(owner_id=…), which re-files the ownership indexessecret(envelope)SecretGrant)EnvelopeSecretsService.share()re-wraps the data key for the new owner's user vault;owner_id/owner_vaultsetThe secret repair never decrypts the value:
share()unwraps the DEK with a dead vault's KEK and re-wraps it. The plaintext is not in the result, the response or the audit (asserted in the Postgres test).What Changed
