📄 Description (English)

Zulip is an open-source team collaboration tool. Prior to commit bf28c82dc9b1f630fa8e9106358771b20a0040f7, the API endpoint for creating a card update session during an upgrade flow was accessible to users with only organization member privileges. When the associated Stripe Checkout session is completed, the Stripe webhook updates the organization’s default payment method. Because no billing-specific authorization check is enforced, a regular (non-billing) member can change the organization’s payment method. This vulnerability affected the Zulip Cloud payment processing system, and has been patched as of commit bf28c82dc9b1f630fa8e9106358771b20a0040f7. Self-hosted deploys are no longer affected and no patch or upgrade is required for them.

🤖 AI Executive Summary

Zulip's API endpoint for card update sessions during upgrades was accessible to regular organization members without proper billing authorization checks, allowing them to change the organization's default payment method. This vulnerability affected Zulip Cloud's payment processing and has been patched in commit bf28c82dc9b1f630fa8e9106358771b20a0040f7.

📄 Description (Arabic)

كانت نقطة نهاية API في Zulip لإنشاء جلسات تحديث البطاقة أثناء تدفق الترقية متاحة للأعضاء العاديين في المنظمة دون فحوصات تفويض محددة للفواتير. عند إكمال جلسة Stripe Checkout المرتبطة، يمكن لأي عضو عادي تغيير طريقة الدفع الافتراضية للمنظمة. تم إصلاح هذا الضعف في نظام معالجة الدفع في Zulip Cloud.

🤖 ملخص تنفيذي (AI)

تطبيق Zulip للتعاون الجماعي كان يسمح لأعضاء المنظمة العاديين بالوصول إلى نقطة نهاية API لجلسات تحديث البطاقة دون فحوصات تفويض محددة للفواتير. يمكن للمستخدمين غير المصرح لهم بالفواتير تغيير طريقة الدفع الافتراضية للمنظمة عند إكمال جلسة Stripe Checkout.
