Summary
XWiki OIDC Authenticator: Users with "view" access can create tokens for any users they can view
Details

Impact

Anyone with VIEW access to a user profile can create a token for that user. If that XWiki instance is configured to allow token authentication, it allows authentication with any user (since users are very commonly viewable, at least to other registered users).

Patches

Version 2.18.2.

Workarounds

The only workaround is to disable token access.
