CVE-2025-49594: XWiki OIDC Authenticator: Users with "view" access can create tokens for any users they can view
(updated )
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).
