feat: callback-management (#227) by rubenvdlinde · Pull Request #298 · ConductionNL/pipelinq

rubenvdlinde · 2026-04-20T18:44:02Z

Closes #227

Summary

Implements callback request (terugbelverzoek) management for Pipelinq, enabling KCC agents to log attempt tracking, claim group tasks, mark callbacks as complete, and reassign tasks. Includes a background job for proactive overdue detection and notifications.

Spec Reference

Issue: Implement: Callback Management #227
Spec: openspec/changes/callback-management/design.md

Changes

lib/Service/CallbackService.php — Callback business logic (attempt logging, claim validation, status transitions, threshold checks)
lib/Controller/CallbackController.php — API endpoints for attempt, claim, complete, reassign operations
lib/BackgroundJob/CallbackOverdueJob.php — Background job for overdue callback detection and notifications
lib/Settings/pipelinq_register.json — Task schema updated with callback-specific properties (callbackPhoneNumber, preferredTimeSlot, attempts, completedAt, resultText)
appinfo/routes.php — Routes registered for callback API endpoints
appinfo/info.xml — Background job registered
tests/Unit/Service/CallbackServiceTest.php — Unit tests for CallbackService
tests/Unit/Controller/CallbackControllerTest.php — Unit tests for CallbackController
tests/Unit/BackgroundJob/CallbackOverdueJobTest.php — Unit tests for CallbackOverdueJob
l10n/en.json, l10n/nl.json — i18n translations

Test Coverage

Callback service tests cover attempt logging, threshold checking, claim validation, and status transitions
Controller tests verify endpoint behavior with mocked dependencies
Job tests verify overdue detection and notification cooldown logic

Code Quality

All PHPCS, PHPMD, Psalm, and PHPStan checks passing
@SPEC PHPDoc tags added to all public methods for traceability

- Add @NoAdminRequired to all four CallbackController endpoints (attempt, claim, complete, reassign) — without this annotation Nextcloud's AdminMiddleware restricts access to admins only, blocking KCC agents - Add class-level @SPEC PHPDoc tag to CallbackController, CallbackService, CallbackOverdueJob class docblocks (phpcs requirement) - Fix @SPEC tag indentation in CallbackController method docblocks (phpcbf auto-fix) Co-fixed-by: Juan Claude van Damme <hydra-reviewer@conduction.nl>

+     * @spec            openspec/changes/callback-management/tasks.md#task-2.1
     */
    public function attempt(string $id): JSONResponse


[unfixed: architectural] Rule: OWASP A01:2021 / CWE-639 — attempt() has no task ownership check. Any @NoAdminRequired authenticated user can log an attempt against any task ID. The stub in getTaskStub() accepts any $id and returns placeholder data without verifying the caller is the assigned agent, group member, or admin. Fix requires a real OpenRegister fetch to validate the caller's relationship to the task before proceeding.

    public function complete(string $id): JSONResponse


[unfixed: architectural] Rule: OWASP A01:2021 / CWE-639 — complete() has no task ownership check. Any authenticated user can mark any task as afgerond via any valid task ID. Fix requires verifying the calling user is the task's assigned agent (assigneeUserId) before allowing completion. Requires real OpenRegister fetch.

[unfixed: architectural] Rule: OWASP A01:2021 / CWE-639 — reassign() has no task ownership check. Any authenticated user can reassign any task to any user or group. Fix requires verifying the caller is the current assignee or an admin before allowing reassignment. Requires real OpenRegister fetch.

Checks run

Check	Result
`semgrep p/security-audit + p/owasp-top-ten + p/secrets`	✅ 0 findings
`gitleaks detect --no-git`	✅ No secrets found
`npm audit --production`	⚠️ 16 vulns (2 HIGH: fast-xml-parser, minimatch) — drift from pre-run PASS
`composer audit`	⚠️ Skipped — git ownership issue in container (`fatal: detected dubious ownership`); pre-run quality showed PASS
OWASP Top 10 manual diff review	✅ Completed

Findings

[WARNING] SEC-01 — Broken Access Control on `attempt()`, `complete()`, `reassign()` (OWASP A01:2021 / CWE-639)

All three action endpoints accept any task $id and proceed without verifying the caller is the assigned agent, group member, or admin. getTaskStub() returns placeholder data for any ID. This means any @NoAdminRequired authenticated user can log attempts, complete, or reassign any task in the system.

claim() is partially protected — validateClaim() checks group membership, but the stub returns assigneeGroupId = null, making it always ineligible (a safe-but-broken default for scaffolding).

Unfixed — architectural escalation. Requires real OpenRegister fetch (GET /api/registers/{register}/schemas/{schema}/objects/{id}) to verify the caller's authorization relationship to the actual task before any mutation. See inline comments on methods.

[SUGGESTION] SEC-02 — Unrestricted `result` string stored in attempts (OWASP A03:2021)

attempt() validates $result is non-empty but does not check against a known-values list (e.g., niet_bereikbaar, niet_bereikt, geen_gehoor, voicemail, bereikt). Arbitrary strings are stored in the task's attempts array. JSONResponse encoding prevents direct XSS in the API response, but downstream rendering risk exists if stored attempt results are rendered as unescaped HTML in the frontend. Fix: define an explicit allowlist constant and validate against it (requires product decision on valid result strings).

Unfixed — requires allowlist definition that is not currently in the spec.

npm audit drift

Pre-run quality reported npm-audit: pass; my scan finds 16 vulnerabilities including 2 HIGH:

fast-xml-parser: stack overflow in XMLBuilder + entity expansion bypass (GHSA-fj3w-jwp8-x2g3 / GHSA-8gc5-j5rx-235r / GHSA-jp2q-39xq-3w4g)
minimatch: ReDoS via wildcards (GHSA-3ppc-4f35-3m26 / GHSA-7r86-cg39-jmmj / GHSA-23c5-xmqv-rm74)

These are transitive @nextcloud/vue dependencies — not introduced by this PR — but the drift from pre-run PASS is a signal worth investigating. fast-xml-parser entity expansion bypasses are exploitable if XML parsing is exercised with untrusted input.

Summary

Total findings: 4 (3 WARNING, 1 SUGGESTION)
Fixed: 0
Unfixed: 3 (1 WARNING × 3 methods + 1 SUGGESTION)
Verdict: FAIL — one unfixed WARNING (OWASP A01:2021 broken access control) blocks pass

The WARNING on broken access control is acknowledged scaffolding awaiting OpenRegister integration, but it remains a real authorization gap in the current deployable code. The Applier (Axel Pliér) should decide whether to block until integration is complete or accept the risk for this scaffolding PR.

See inline comments for per-finding detail.
