Published Oct 1, 2024 · Updated Apr 8, 2026

Stored XSS in 123.chat - Video Chat 1.3.1 and earlier allows remote attackers to inject scripts into pages viewed by site users. Wordfence attributes the flaw to insufficient input sanitization and output escaping but does not identify the affected parameter, request handler, or rendering function. No authentication is required to store the payload; the script executes in each visitor's browser when an injected page is accessed.
