Cross-site scripting in Wikimedia Foundation MediaWiki ConfirmAccount 1.39 through 1.43 allows remote authenticated users to execute script. Multiple account-request and confirmation paths render attacker-influenced parameters through five system messages without output encoding. Exploitation requires low-privileged access and another user to view affected output, placing browser-context data and actions at risk.
