| Mô tả | I reported a vulnerability in bookstack (https://github.com/BookStackApp/BookStack) which was promptly patched in https://github.com/BookStackApp/BookStack/releases/tag/v26.03.1
I am requesting a CVE.
Description:
The finding is confirmed by direct source code inspection. In `ExportFormatter.php`, the `chapterToMarkdown()` method at line 317 iterates over `$chapter->pages` — the raw Eloquent relationship that returns all pages associated with the chapter **with no permission scoping whatsoever**.
This is in direct contrast to every other chapter export method in the same class:
The `getVisiblePages()` method on the `Chapter` model applies `->scopes('visible')` which triggers permission filtering through the `PermissionApplicator`, and also orders by draft status and priority. The raw `$chapter->pages` relationship bypasses all of this, exposing every page in the chapter regardless of the current user's permissions. |
