Description
### 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.
