# Beyondseo WordPress plugin: Contributors can manage site-wide redirects

Versions up to and including 1.3.6 of the Beyondseo plugin grant the Contributor role capabilities that should be admin-only, so any Contributor can create, edit or delete site-wide 301/302 redirects. An attacker can redirect visitors on any path, including checkout or login pages, to a site they control.

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

## How to check

- Check the installed Beyondseo plugin version in the WordPress admin Plugins screen or with `wp plugin get beyondseo --field=version`
- Review Contributor and other non-admin user accounts on the site with `wp user list --role=contributor`
- Look for unexpected redirect rules in the Beyondseo redirect manager screen

## Fix

- Update the Beyondseo plugin to a version later than `1.3.6` once the vendor publishes one (unknown from the sources)
- Until patched, deactivate the plugin or remove Contributor accounts that do not need access
- Audit existing redirect rules for unexpected targets

## From the sources

The Beyondseo plugin for WordPress is vulnerable to unauthorized access in versions up to, and including, 1.3.6. This is due to the plugin permanently granting the 'rankingcoach_write_redirectManager' (and sibling rankingcoach_write_* module capabilities) to the Contributor role via BaseModule::defineCapabilities(), whose default role list includes 'contributor', combined with the module's REST endpoints (registered through BaseSubmoduleApi::registerRouteCreate/registerRouteEdit/registerRouteDelete) authorizing state-changing requests solely through checkPermissionsPost(), which only calls current_user_can('rankingcoach_write_<module>') and performs no admin capability, ownership, or additional nonce check inside the callback. This makes it possible for authenticated attackers, with Contributor-level access and above, to elevate their privileges to effectively that of an Administrator with respect to site-wide redirect management — creating, updating, or deleting 301/302 redirects that RedirectManagerHooks::handleRedirects() executes for every frontend visitor on template_redirect, allowing hijacking of arbitrary paths (including /checkout, /wp-login.
