Summary

XWiki OIDC versions starting from 2.17.1 and prior to 2.18.2 allows anyone with VIEW access to a user profile to create a token for that user. If the XWiki instance is configured to allow token authentication, this allows authentication as any user. Version 2.18.2 contains a patch.

Risk Assessment

An attacker could gain access to other users' accounts, including administrators, if they can view their profiles. This leads to full account takeover and potential compromise of the entire XWiki instance.

Recommendation

Update XWiki OIDC to version 2.18.2 or later. As a temporary workaround, disable token access in the XWiki configuration.

Original NVD description (English source)

XWiki OIDC has various tools to manipulate OpenID Connect protocol in XWiki. Starting in version 2.17.1 and prior to version 2.18.2, 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). Version 2.18.2 contains a patch. As a workaround, disable token access.
