# WP Remote Users Sync: synced sites can grant themselves administrator rights

Link for people: https://infrastack.ai/live/CVE-2026-123097 (this .md is for agents)

The WP Remote Users Sync WordPress plugin before 2.2.1 does not limit which account fields a synchronised site can set when creating or updating users. A site holding the shared synchronisation keys can assign the administrator role, change any existing account and write arbitrary user metadata.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed version of the WP Remote Users Sync plugin in the WordPress admin under Plugins; anything below `2.2.1` is affected.
- Review which sites hold the plugin's shared synchronisation keys and whether any of them are untrusted.

## Fix

- WP Remote Users Sync: move to `2.2.1` or later.

## Timeline

- 2026-11-13T06:42:16+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-123097

## From the sources

The WP Remote Users Sync WordPress plugin before 2.2.1 does not restrict which account fields a synchronised site may set when it creates or updates users, allowing a site holding the shared synchronisation keys to assign the administrator role, modify any existing account and write arbitrary user metadata, bypassing the receiving site's role and metadata restrictions.
