CVE-2024-50470Network attack vector

Authenticated script execution in visitors' browsers

Published Oct 28, 2024 · Updated May 11, 2026

DOM-based XSS in Themes4WP YouTube External Subtitles 1.0 and earlier allows remote authenticated users to execute script in a visitor's browser. The public record identifies improper neutralization during DOM-based page generation but does not disclose the affected file, function, DOM source, or sink. Low-privileged WordPress access and a visitor loading affected content are required; successful exploitation runs attacker-controlled script in that visitor's browser context.
