| npm | @payloadcms/next | < 3.78.0 | 3.78.0 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
A stored Cross-site Scripting (XSS) vulnerability existed in the admin panel. An authenticated user with write access to a collection could save content that, when viewed by another user, would execute in their browser.
Consumers are affected if ALL of these are true:
- Payload version **< v3.78.0**
- At least one collection with versions enabled
- An authenticated user has `create` or `update` access to that collection
### Patches
This vulnerability has been patched in **v3.78.0**. Output encoding has been added to prevent user-supplied content from being interpreted as markup.
Users should upgrade to **v3.78.0** or later.
### Workarounds
If consumers cannot upgrade immediately:
- Restrict `create` and `update` access to versioned collections to trusted roles only.
