The issue is related to insufficient authentication checks for executed requests in the XWiki Platform, allowing cross-site request forgery. This can lead to remote code execution through script macros when a user with programming rights interacts with the platform, impacting the integrity, availability, and confidentiality of the XWiki installation. For regular cookie-based authentication, the issue is mitigated by SameSite cookie restrictions, but these are not enabled by default in Firefox and Safari as of March 2023.
