Detection Guidance

Detection of CVE-2025-65036 involves identifying if your system is running XWiki Remote Macros version 1.27.0 or earlier, which are vulnerable. Since the vulnerability is exploited by creating pages with specific macros executing Velocity templates without permission checks, you can check for the presence of the 'detailssummary' macro usage in your XWiki pages and verify if any pages contain asynchronous macro calls embedding Groovy code. There are no specific commands provided in the resources, but you can audit your XWiki instance by searching for pages containing the 'detailssummary' macro and reviewing user permissions and recent page edits for suspicious macro usage. Upgrading to version 1.27.1 or later is recommended to remediate the issue. [1]
