The specifics of these vulnerabilities are not detailed in this advisory, but successful exploitation could compromise the integrity and confidentiality of the affected XWiki instance. Given the lack of CVE details, defenders should focus on detecting post-compromise activities related to file manipulation and data exfiltration originating from XWiki servers.
