Affected packages

• Maven org.xwiki.contrib.oidc:oidc-authenticator: >= 2.17.1, < 2.18.2 → fixed in 2.18.2

Description

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.
