Description

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.
