CRITICAL FIX: Newsletter subscription was returning "Forbidden" error
because the CSRF protection was incorrectly configured.
Root cause:
- CSRF cookie was set with httpOnly: true
- JavaScript cannot read httpOnly cookies
- Frontend couldn't extract token to send in X-CSRF-Token header
- Double-submit CSRF pattern requires client to read the cookie
Changes:
- csrf-protection.middleware.js: Set httpOnly: false (required for double-submit pattern)
- blog.js: Extract CSRF token from cookie and include in X-CSRF-Token header
Security Note: This is the correct implementation per OWASP guidelines
for double-submit cookie CSRF protection. The cookie is still protected
by SameSite: strict and domain restrictions.
Fixes: #newsletter-subscription-forbidden-mobile
- Create Economist SubmissionTracking package correctly:
* mainArticle = full blog post content
* coverLetter = 216-word SIR— letter
* Links to blog post via blogPostId
- Archive 'Letter to The Economist' from blog posts (it's the cover letter)
- Fix date display on article cards (use published_at)
- Target publication already displaying via blue badge
Database changes:
- Make blogPostId optional in SubmissionTracking model
- Economist package ID: 68fa85ae49d4900e7f2ecd83
- Le Monde package ID: 68fa2abd2e6acd5691932150
Next: Enhanced modal with tabs, validation, export
