Stored XSS via untrusted Live Data HTML

Published Mar 2, 2023 · Updated Mar 5, 2025

Stored XSS in XWiki Platform allows remote authenticated users without script rights to execute script via a crafted Live Data macro. The Live Data HTML displayer renders attacker-controlled entry values as trusted HTML because advanced macro content was not marked untrusted. A victim must view the stored content; affected ranges are 12.10 before 13.10.10, 14.0 before 14.4.7, and 14.5 before 14.9.
