ApostropheCMS is an open-source Node.js content management system. Prior to 4.33.0, the notification module exposes PATCH and DELETE REST endpoints that perform operations directly on the underlying MongoDB collection without verifying that the requester is authenticated or owns the target notification. As a result, an unauthenticated attacker who obtains a valid notification ID can modify or permanently delete another user's notification. This issue is fixed in version 4.33.0.

GHSA-vwwx-px9w-crrc — ApostropheCMS: Missing Authorization on Notification PATCH/DELETE Endpoints

Affected: npm: apostrophe

## Summary

The notification module exposes `PATCH` and `DELETE` REST endpoints that perform operations directly on the underlying MongoDB collection without verifying that the requester is authenticated or owns the target notification.

As a result, an unauthenticated attacker who obtains a valid notification ID can modify or permanently delete another user's notification.

## Affected Code

**File**

```text packages/apostrophe/modules/@apostrophecms/notification/index.js ```

```javascript // restApiRoutes async patch(req, _id) { const dismissed = self.apos.launder.boolean(req.body.dismissed);

if (dismissed) { await self.emit('beforeSave', req, { _id, dismissed });

await self.db.updateOne( { _id }, { $set: { dismissed }, $currentDate: { updatedAt: true } } ); } },

async delete(req, _id) { await self.db.deleteMany({ _id }); } ```

Unlike the `GET` notification route, these handlers do **not** verify:

- Authentication (`req.user`) - Ownership (`userId === req.user._id`) - Authorization or permissions

Instead, the supplied `_id` is used directly against the raw MongoDB collection.

---

## Root Cause

The notification REST endpoints perform database operations directly using `self.db` without enforcing authentication or authorization.

While the framework provides permission primitives (`req.user`, ownership checks, and `apos.permission`), these endpoints never invoke them. As a result, any request reaching thes…
