CVE-2025-27603Public exploitNetwork attack vector

Authenticated code execution via unescaped translations

Published Mar 7, 2025 · Updated Mar 7, 2025

Code injection in XWiki SAS Confluence Migrator Pro before 1.2.0 allows remote authenticated users to execute arbitrary code. MigrationSheet.xml renders localization values directly into template markup without XML escaping, so injected XWiki and Groovy directives are evaluated. A user able to create pages and a USER-scoped translation object can run code with the XWiki server's privileges.
