The login endpoint does not regenerate the session ID after successful authentication. The passport.authenticate() callback directly redirects without calling req.session.regenerate(). This allows an attacker who obtains a pre-authentication session ID to reuse that session ID after the victim authenticates. The affected code is Parse-Dashboard/Authentication.js:87. This change is the fix I would apply.

Reference: CWE-384

🚀 Thanks for opening this pull request! We appreciate your effort in improving the project. Please let us know once your pull request is ready for review.

Tip

  • Keep pull requests small. Large PRs will be rejected. Break complex features into smaller, incremental PRs.
  • Use Test Driven Development. Write failing tests before implementing functionality. Ensure tests pass.
  • Group code into logical blocks. Add a short comment before each block to explain its purpose.
  • We offer conceptual guidance. Coding is up to you. PRs must be merge-ready for human review.
  • Our review focuses on concept, not quality. PRs with code issues will be rejected. Use an AI agent.
  • Human review time is precious. Avoid review ping-pong. Inspect and test your AI-generated code.

Note

Please respond to review comments from AI agents just like you would to comments from a human reviewer. Let the reviewer resolve their own comments, unless they have reviewed and accepted your commit, or agreed with your explanation for why the feedback was incorrect.

Caution

Pull requests must be written using an AI agent with human supervision. Pull requests written entirely by a human will likely be rejected, because of lower code quality, higher review effort and the higher risk of introducing bugs. Please note that AI review comments on this pull request alone do not satisfy this requirement. Our CI and AI review are safeguards, not development tools. If many issues are flagged, rethink your development approach. Invest more effort in planning and design rather than using review cycles to fix low-quality code.

📝 Walkthrough

Walkthrough

The login handler now processes Passport results with an explicit callback and regenerates the session before logging in a successful user. DateTimePicker constructs dates from local or UTC components according to mode. Most other changes reformat existing code without changing its described behavior.

Changes

Application updates

Layer / File(s) Summary
Login authentication and session handling
Parse-Dashboard/Authentication.js
The handler forwards authentication and session-regeneration errors to Express. It redirects failed logins to the existing failure URL. For a successful user, it regenerates the session, logs in the user, and redirects to the requested destination.
Local and UTC date construction
src/components/DateTimePicker/DateTimePicker.react.js
commitTime and the calendar date-change handler now construct local dates in local mode and use UTC components in non-local mode.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~25 minutes

Suggested reviewers: mtrezza

Merge Risk: 🔵 Low · up to 2de2d

Failed logins still lose their specific error and one-time-password feedback. Restore those messages before merging, or explicitly accept this bounded regression.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 2de2d

The new session-handling flow appears to block the normal login path for users who need a one-time password. It does not show an authentication bypass, but the affected users may be unable to access the dashboard. The change has not been verified by an automated check.

Retained concerns

  • High · security · inferred: The custom authentication callback redirects failed logins without preserving the error message that the login UI uses to reveal its OTP field. Users requiring MFA may be unable to complete the normal login flow.
Security review details

Security Blast Radius

  • inferred — The affected authentication flow is the dashboard login for configured users, including users requiring an OTP. The evidence does not establish a broader service or tenant exposure.

Security Findings and Attack Paths

  • inferred — A user submitting valid credentials without an OTP receives an authentication failure, but the new callback does not pass its one-time-password message to the UI. This is a control-availability regression, not evidence that an attacker can bypass MFA.

Trust Boundaries and Controls

  • observed — The handler checks the CSRF token before processing credentials and initiates a new session before establishing the authenticated Passport login. A failed regeneration or login is not followed by the success redirect.

Hardening Proposals

  • proposed — Preserve the authentication failure message when using a custom Passport callback, and verify the full MFA and session-rotation flows across success, failure, and session-store errors.

Full details: Engage In Review Feedback

Explanation

The review feedback remains unresolved. The posted comment requests that the Passport callback accept info and flash info.message before redirecting on !user. The current diff still uses (err, user) and redirects without req.flash; the follow-up commit does not modify Parse-Dashboard/Authentication.js. No evidence shows that the reviewer retracted the feedback.

Remove the duplicate session regeneration.

Passport 0.7.0 req.logIn regenerates and saves the session before its callback. The explicit call adds another session-store operation and failure point without improving session-fixation protection.

Suggested fix
-        req.session.regenerate((err) => {
-          if (err) { return next(err); }
-          req.logIn(user, (err) => {
+        req.logIn(user, (err) => {
             if (err) { return next(err); }
             res.redirect(`${self.mountPath}${redirect}`);
-          });
         });

Restore local authentication failure messages.

The custom Passport callback bypasses Passport’s automatic failureFlash handling. The local strategy returns messages for invalid credentials and one-time-password failures, but the !user branch redirects without flashing info.message. The GET /login handler reads req.flash('error'), so failed attempts lose their specific message.

Suggested fix
-      return passport.authenticate('local', { failureRedirect, failureFlash: true }, (err, user) => {
+      return passport.authenticate('local', { failureRedirect, failureFlash: true }, (err, user, info) => {
         if (err) { return next(err); }
-        if (!user) { return res.redirect(failureRedirect); }
+        if (!user) {
+          if (info?.message) { req.flash('error', info.message); }
+          return res.redirect(failureRedirect);
+        }

✅ Review Feedback Addressed

I've automatically addressed 2 review comment(s):

The code review feedback from coderabbitai suggests removing the duplicate session regeneration. According to the review, Passport 0.7.0's req.logIn already regenerates and saves the session before its callback, making the explicit req.session.regenerate() call redundant. This removes an unnecessary session-store operation and potential failure point while still providing the same session-fixation protection.

I need to read the current file first to understand its exact state, then modify it to remove the explicit session regeneration call.
