How the CVE Works
The vulnerability arises due to improper input sanitization in two XWiki templates (job_status_json and distribution). An attacker crafts malicious URLs containing JavaScript payloads in parameters like translationPrefix, extensionId, and extensionVersionConstraint. When a victim visits the manipulated URL, the injected script executes in their browser, leveraging their session permissions. This allows session hijacking, data theft, or unauthorized actions.
