fix(auth, a11y): oauth redirect validation and focus-trap test typing - #840
Conversation
Issue Pi-Defi-world#785 - W2-F-034: Validate OAuth callback redirect target - Added getSafeOAuthReturnPath() validator to prevent open redirect vulnerabilities - Validates returnPath starts with / and is not protocol-relative (//) or absolute URL - Rejects javascript:, data:, http://, https:// schemes - Falls back to / for any invalid redirect path Issue Pi-Defi-world#779 - W2-F-028: Clean up focus-trap hook test typing - Removed unused 'vi' import from vitest - Replaced 6 'any' type casts with proper React.RefObject<HTMLDivElement> typing - Improved type safety across all 6 test cases - Ensures test code passes strict linting requirements

📝 WalkthroughWalkthroughThe focus trap test file now follows Vitest-compatible formatting, removes an unused import, and uses explicitly typed mutable refs. Existing focus-wrap, inactive-state, disabled-element, and hidden-element coverage remains unchanged. ChangesFocus trap test cleanup
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The inactive focus-trap test does not dispatch its keyboard event, so a regression could pass unnoticed. This is a bounded test-quality risk, and the PR is otherwise mergeable with explicit follow-up. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Dispatch the event in the inactive-state test.
Line 103 always passes because event is never dispatched. Dispatch it through container and assert that focus remains on lastButton. The test will then detect a regression that traps focus when isActive is false.
Proposed fix
// Should not prevent default when inactive
+ act(() => {
+ container.dispatchEvent(event);
+ });
expect(event.defaultPrevented).toBe(false);
+ expect(document.activeElement).toBe(lastButton);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Problem
The OAuth callback page reads the redirect target directly from
sessionStoragewithout validation, creating an open redirect vulnerability. Any code with sessionStorage access can control post-login navigation.Root cause:
app/[locale]/auth/oauth/callback/page.tsxlines 38-40returnPath = sessionStorage.getItem('oauth_return_path') || '/'router.replace(returnPath)// Unvalidated redirectSolution

External/malicious return paths are rejected and safely redirected to home.
Issue #779 - W2-F-028: Clean Up Focus-Trap Hook Test Typing
Problem
Focus-trap test file had quality issues:
viimport from vitest (line 1)(as any)type casts (lines 28, 52, 77, 96, 115, 159)This reduced test quality and failed linting checks.
Solution
viimportanytype casts with properReact.RefObject<HTMLDivElement>typingImpact
Test code now passes strict ESLint and TypeScript linting.
Files Modified
