CVE-2023-28493Network attack vector

Subscriber-level browser script execution via reflected input

Published May 8, 2023 · Updated Apr 28, 2026

Reflected XSS in Macho Themes NewsMag 2.4.4 and earlier allows remote authenticated users to execute scripts via crafted requests. Public sources do not identify the affected parameter, code path, or exact output operation that reflects untrusted input into an HTML response. Subscriber-level access and victim interaction are required, and successful exploitation executes attacker-controlled script in the victim's browser under the site's origin.
