@payloadcms/next has Stored XSS in Admin Panel
Quick fix
GHSA-mmxc-95ch-2j7c — @payloadcms/next: upgrade to the fixed version with the command below.
npm install @payloadcms/next@3.78.0Details
### 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.
