CVE-2023-37908 is a cyber vulnerability that affects XWiki Rendering. It allows for the injection of arbitrary HTML code and cross-site scripting via invalid attribute names. This vulnerability can be exploited through the link syntax in any content supporting XWiki syntax, such as comments. When a user hovers over a malicious link, the injected JavaScript code is executed within the user session. If the affected user has programming rights, this vulnerability enables server-side code execution with programming rights, potentially impacting the confidentiality, integrity, and availability of the XWiki instance. The issue has been addressed in XWiki versions 14.10.4 and 15.0 RC1 by implementing proper attribute cleaning and validation. The vulnerability has a base severity rating of CRITICAL and poses a high risk to organizations due to its potential for unauthorized code execution and data compromise.
