GHSA-6gf5-c898-7rxp: Improper Neutralization of Script in Attributes in XWiki (X)HTML renderers
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.
