CVE-2024-47348Network attack vector

Reflected XSS via unsanitized request input

Published Oct 6, 2024 · Updated Apr 28, 2026

Reflected XSS in YellowPencil Visual CSS Style Editor 7.6.4 and earlier allows remote attackers to execute script via a crafted URL. The public advisory attributes the flaw to insufficient input sanitization and output escaping but does not identify the affected parameter or code path. Exploitation requires no account, but a user must open the crafted link; the injected script then runs in that user's browser context.
