CVE-2024-54040Network attack vector

Authenticated browser script execution via unneutralized form input

Published Dec 10, 2024 · Updated Dec 10, 2024

Stored XSS in Adobe Connect 12.6, 11.4.7 and earlier allows remote authenticated users to execute scripts in victims' browsers. Vulnerable form fields store attacker-supplied JavaScript and emit it into a page without adequate neutralization when that page is opened. The attack requires low-privileged access and a victim opening the affected page; the script runs in that browser's Adobe Connect context.
