CVE-2024-4302Network attack vector

Stored XSS via unfiltered chat messages

Published Apr 29, 2024 · Updated Aug 1, 2024

Stored XSS in Super 8 Livechat SDK 4.5.0 and earlier allows remote attackers to run JavaScript when a recipient views a chat message. The chat box accepts attacker-supplied JavaScript without properly filtering the input and stores it for delivery to the message recipient. No authentication is required to submit the payload, but execution requires a recipient to view the crafted message, exposing data and permitting actions in that browser context.
