Stored XSS via unvalidated Cloud callback
Published Jul 24, 2024 · Updated Apr 8, 2026
Cross-site request forgery in LiteSpeed Technologies LiteSpeed Cache 6.2.0.1 and earlier allows remote attackers to inject stored JavaScript. The Cloud callback handler accepts a forged request that changes the stored QUIC.cloud token because it does not validate a WordPress nonce. An administrator must be authenticated and induced to open an attacker-controlled link; the resulting script executes in the site's administrative context.
