CVE-2024-45803Public exploitNetwork attack vector

Reflected XSS via unescaped button label

Published Sep 17, 2024 · Updated Sep 18, 2024

Reflected XSS in WireUI before 1.19.3 and 2.0.0 through 2.1.2 allows remote attackers to execute JavaScript via a crafted label. The button endpoint dynamically renders the label query parameter into its HTML response without neutralizing injected markup. Execution requires a victim to open the crafted endpoint URL, exposing browser-accessible data and actions within the affected site's context.
