Impact HTML rendering didn't check for dangerous attributes/attribute values. This allowed cross-site scripting (XSS) attacks via attributes and link URLs, e.g., supported in XWiki syntax. Patches This has been patched in XWiki 14.6 RC1. Workarounds There are no known workarounds apart from upgrading to a fixed version.
