What

Ports the scheduler half of 6.4.9's #5593 from release/6.5.0 (dd941d6, Pavel) to next. The other half, RuntimeTenant, came in with #5888.

Scheduler access was governed by its own scheduler.action permission. The admin has no way to grant it, so only full-access users could list, read or cancel scheduled actions. On a non-root tenant, where users usually have CMS or Website Builder roles rather than full access, scheduling didn't work. A user with cms.* permissions got NotAuthorizedError from the scheduler on next.

This PR removes the scheduler.action permission. Access now follows the permissions of the app that owns the scheduled action:

  • SchedulerPermissions becomes a multi-registered abstraction (canHandle(namespace), canRead(), onlyOwnRecords()). SchedulerPermissionsResolver picks the one for an action's namespace.
  • api-headless-cms-scheduler registers CmsSchedulerPermissions, which checks cms.contentEntry for Cms/Entry/* actions.
  • api-website-builder-scheduler registers WbSchedulerPermissions, which checks the WB page publish permissions for WebsiteBuilder/Type/* actions.
  • Get, get-target, list and cancel ask the resolver for the action's namespace. Execute now reports a failure when it can't record an error on the scheduled action, where before it ignored that.

Fail closed when no app owns a namespace

The port as it came from 6.5.0 skipped the permission check whenever no app claimed a namespace, or when listing without one. The last commit makes the resolver fall back to full access only in those cases, and drops the undefined checks in the use cases. The same commit goes to release/6.5.0 as #5908, where it also makes the self-hosted scheduler server list pending actions without authorization at startup. That package doesn't exist on next.

Adapted for next

  • next registers features with createFeature instead of context plugins, so the three new registrations go into CmsSchedulerFeature, WebsiteBuilderSchedulerFeature and SchedulerFeature. 6.5.0 does this in the deleted context.ts files.
  • The use cases keep next's ScheduledActionModelProvider, where 6.5.0 injects the model directly. They also keep next's doc comments, which 6.5.0 had removed (separate commit).
  • The commit's api-scheduler ExecuteScheduledActionUseCase test is left out, because 6.5.0 removed it again in caedf7a as incompatible. 6.5.0's nonRootTenantScheduling test is also left out. It runs on the root tenant with full access, the same steps as next's existing actionHandlers test, so it adds no coverage.

Tests

api-headless-cms-scheduler/__tests__/schedulerPermissions.test.ts is new:

  • A user with cms.* and no full access schedules a publish, then lists and reads it. This failed on next with NotAuthorizedError before the fix.
  • A user with only fm.* can't read a CMS scheduled action (Scheduler/NotAuthorized).
  • A CMS user can't list without a namespace, or under a namespace no app claims. A full-access user, and code running without authorization, can. Without the fail-closed commit, the two "can't" cases fail.

Checks

  • yarn build passes.
  • Tests pass for api-headless-cms-scheduler (7), api-scheduler (1) and api-website-builder-scheduler (4).
  • adio, sync-dependencies, oxfmt and oxlint are clean. The webiny package generator changes nothing. No references to scheduler.action or the old schema are left in the repo.

Not covered by a test: WbSchedulerPermissions. It has the same structure as the CMS one, and the existing Website Builder scheduler tests pass.

Summary by CodeRabbit

  • New Features
    • Scheduled-action access now follows the permissions for the action’s content-management or website-builder namespace, including read access and restrictions to actions created by the current identity.
    • Listing, viewing, retrieving, and canceling scheduled actions now apply namespace-specific access checks. Actions without a matching namespace require full access.
  • Bug Fixes
    • If saving an error status fails after a handler is unavailable or execution throws an error, the save failure is now reported with context; otherwise, the original handler or execution error is returned.

…sions refactor

Port of #5593 from release/6.4.9 (Phase 4a). Replaces monolithic
SchedulerPermissions with namespace-based SchedulerPermissionsResolver.
CMS and WB schedulers provide their own permission implementations.

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

(cherry picked from commit dd941d6)

Adapted for next: next registers features with createFeature instead of context plugins, so CmsSchedulerPermissions, WbSchedulerPermissions and SchedulerPermissionsResolver are registered in CmsSchedulerFeature, WebsiteBuilderSchedulerFeature and SchedulerFeature. The use cases keep next's ScheduledActionModelProvider. RuntimeTenant, the other half of 6.4.9's #5593, is already on next (#5888). The api-scheduler ExecuteScheduledActionUseCase test from this commit is left out, as 6.5.0 removed it again in caedf7a.
…entry permissions

A user with CMS entry permissions but no full access, the usual role on a
non-root tenant, can now list and read the actions they scheduled. A user
without CMS permissions still can't read CMS scheduled actions. The first case
failed on next with NotAuthorizedError before the previous commit.

🚓 Slop Cop

⚠️ 3 thing(s) worth a look before merging.

PR footprint matches its stated scope (scheduler permission port), with only minor style nits around an inline any and an inline cast-as-call-argument in ExecuteScheduledActionUseCase.ts.

🚨 Should this be in the PR?

🟡 Low — Footprint matches stated intent

The diff (+328/-62 across 15 files) is coherent with the described port: new permission abstractions, resolver, feature registrations, and a new test file. No unrelated files, no large deletions out of proportion to the change, no secrets, debug code, or merge conflict markers found.

📏 Code-style rule checks

🟠 Medium — Inline cast via as unknown as in ExecuteScheduledActionUseCase.ts

packages/api-scheduler/src/features/ExecuteScheduledAction/ExecuteScheduledActionUseCase.ts adds two blocks returning Result.fail({ ...updateResult.error, message: ... } as unknown as UseCaseAbstraction.Error). Per prefer-type-annotation-over-cast.md, a real cast should be given its own const first instead of being inlined into the Result.fail(...) call argument; this also doubles as a nested-call-arguments concern (no-nested-call-arguments.md) since the cast expression is built inline as a call argument.

🟡 Low — any cast in CmsSchedulerPermissions.ts

packages/api-headless-cms-scheduler/src/features/permissions/CmsSchedulerPermissions.ts line return !permissions.some((p: any) => !p.own); uses an inline any parameter type instead of a proper type annotation. This isn't strictly the cast rule (prefer-type-annotation-over-cast.md) since it's a parameter annotation rather than an as cast, so flagged only as low-confidence/minor; consider typing p properly instead of any.

Automated, non-blocking heads-up from an LLM. It can be wrong — use your judgment. Regenerates on every push.

📝 Walkthrough

Walkthrough

The scheduler now resolves permissions by namespace. CMS and website-builder features register scheduler permission handlers. Scheduled-action use cases apply the resolved read and ownership checks. Execution paths also return errors when an error-state update fails.

Changes

Namespace-aware scheduler permissions

Layer / File(s) Summary
Permission contract and resolver
packages/api-scheduler/src/features/permissions/abstractions.ts, packages/api-scheduler/src/features/permissions/SchedulerPermissionsResolver.ts, packages/api-scheduler/src/domain/permissionsSchema.ts, packages/api-scheduler/src/features/permissions/feature.ts, packages/api-scheduler/src/SchedulerFeature.ts
The scheduler replaces its schema-based permissions feature with a namespace-based permission contract and resolver. When no handler claims a namespace, the fallback permits reads only when authorization is disabled or the identity has full access. SchedulerFeature registers the resolver directly.
CMS and website-builder permission handlers
packages/api-headless-cms-scheduler/src/features/permissions/CmsSchedulerPermissions.ts, packages/api-headless-cms-scheduler/src/CmsSchedulerFeature.ts, packages/api-website-builder-scheduler/src/features/permissions/WbSchedulerPermissions.ts, packages/api-website-builder-scheduler/src/WebsiteBuilderSchedulerFeature.ts, packages/api-headless-cms-scheduler/__tests__/schedulerPermissions.test.ts
CMS and website-builder features register handlers that delegate scheduler permission checks to their respective permission systems. CMS tests cover permitted and denied retrieval, namespace-based listing, and listing without a namespace for full-access and authorization-disabled identities.
Namespace checks in scheduled-action use cases
packages/api-scheduler/src/features/CancelScheduledAction/CancelScheduledActionUseCase.ts, packages/api-scheduler/src/features/GetScheduledAction/GetScheduledActionUseCase.ts, packages/api-scheduler/src/features/GetTargetScheduledAction/GetTargetScheduledActionUseCase.ts, packages/api-scheduler/src/features/ListScheduledActions/ListScheduledActionsUseCase.ts
These operations resolve permissions for the relevant namespace and apply read and ownership checks. Listing selects the exact namespace or namespace prefix.
Scheduled-action execution error updates
packages/api-scheduler/src/features/ExecuteScheduledAction/ExecuteScheduledActionUseCase.ts
When handler lookup or execution fails, the use case checks the scheduled-action update result. It returns the update error if the update fails.

Merge Risk: 🔵 Low · up to 3f3be

Scheduler access through the inspected request route remains namespace-scoped. Error-update failures still return plain objects rather than typed errors; this is a bounded integration risk to address or explicitly accept before merging.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 3f3be

The restrictive fallback and namespace checks preserve important controls, but the new CMS handler does not preserve model-specific access restrictions. A user authorized for one CMS model can potentially inspect and cancel schedules belonging to other models. The demonstrated exposure concerns scheduler metadata and cancellation, not a general ability to read or publish CMS content.

Retained concerns

  • High · security · inferred: The new CMS handler authorizes every Cms/Entry/* namespace from the presence of any cms.contentEntry permission, without checking the target model, related group/model restrictions, or read/action bits. A model-restricted identity with a non-own entry permission can therefore list another model's schedule metadata and use the returned identifiers to cancel those schedules. Exact namespace matching does not prevent this because the caller supplies the other model's valid namespace, and the private schedule model does not enforce the original target model's ACL. This expands access beyond the former scheduler permission gate.
Security review details

Security Blast Radius

  • inferred — The supported attack scope is CMS scheduled actions available within the request's storage scope, potentially spanning all CMS model namespaces. GraphQL exposes schedule identifiers, titles, targets, scheduling identities, and timing; cancellation can prevent planned publish or unpublish actions. Cross-tenant access, arbitrary publication, and unrestricted CMS content reads were not established.

Security Findings and Attack Paths

  • inferred — An authenticated CMS identity restricted to model A, but holding a non-own cms.contentEntry permission, can request the exact Cms/Entry/modelB namespace. The handler accepts the permission without evaluating model B access, list omits the creator restriction, and returned schedule identifiers can reach cancellation through the same authorization gate. This is a source-supported late-discovered concern, distinct from the rejected prefix-routing candidate; no runtime exploit was executed.

Trust Boundaries and Controls

  • observed — The schedule model is private and built with authorization disabled. CMS access control consequently grants its full entry ACL rather than evaluating the original scheduled target's model restrictions. Generic CMS delete checks therefore do not provide a second target-model authorization boundary after the scheduler handler.
  • observed — The inspected execution path resolves the event tenant, executes inside that tenant context, and adopts the persisted scheduledBy identity while authorization is disabled. These are internal execution controls, not evidence that external scheduler callers inherit execution authority.

Resilience and Maintainability Implications

  • observed — Execution deletes the persisted action after handler success and returns failure when error-state persistence fails. The inspected Lambda consumer throws failed results, as it did for the original handler failure. The PR changes reported errors, but does not establish a new retry or repeated-effect transition.

Hardening Proposals

  • proposed — Bind CMS scheduler authorization to the model extracted from the namespace, preserving related group/model access and ownership restrictions before returning schedule data or performing cancellation. Define cancellation authority explicitly rather than treating permission-array presence as sufficient.

…ases

The cherry-pick of dd941d6 also brought over 6.5.0's removal of several doc comments (the Flow headers, the namespace check note, the already-deleted entry note). They still describe the code, so they stay.

…ed action's namespace

SchedulerPermissionsResolver.forNamespace() returned undefined when no app
claimed the namespace, and the use cases treated that as "no check". So
listing without a namespace, or getting, listing or cancelling under a
namespace no app registers permissions for, skipped the permission check
completely. The scheduler.action permission this replaced always applied.

The resolver now always returns permissions. When no app claims the
namespace, or there is none, it falls back to one that only lets full-access
identities and code running without authorization through. The use cases
drop their undefined checks.

api-scheduler-server lists every pending action at startup, with no
namespace, to re-arm their timers. That's a system task, so it now runs
without authorization and still sees every action.

(cherry picked from commit c391add, #5908 on release/6.5.0)

On next the api-scheduler-server part drops out, because that package doesn't exist here. The fallback test cases are written for next's scheduler test handler.
