CVE-2025-48063
📋 TL;DR
A bug in XWiki's required rights enforcement allows users with edit rights to set programming rights as required rights on documents. If a user with programming rights then edits that document, it gains programming rights, potentially enabling remote code execution. This affects XWiki 16.10.0 through 16.10.3.
