CVE-2024-11321Network attack vector

Browser script execution via reflected input

Published Dec 6, 2024 · Updated Jun 2, 2026

Reflected XSS in Hi e-learning HiLMS before 06.12.2024 allows remote attackers to execute script in a victim's browser. The CNA and referenced government advisory do not identify the affected endpoint or input, so the precise reflection and missing encoding operation are undisclosed. Exploitation requires a victim to open an attacker-crafted request; successful script execution can read or modify data available to that browser session.
