CVE-2024-43792Public exploitNetwork attack vector

Stored XSS via script-bearing iframe data URLs

Published Sep 2, 2024 · Updated Sep 3, 2024

Stored XSS in Halo before 2.17.0 allows remote attackers to execute JavaScript in a user's browser through crafted editor content. The editor permits an iframe whose data URL embeds script-bearing HTML, and the saved content later renders that script without neutralization. Exploitation requires a user to view the stored page; the script runs in that viewer's browser context and can read or alter accessible page data.
