CVE-2024-39663Network attack vector

Stored script execution in users' browsers

Published Aug 1, 2024 · Updated Apr 28, 2026

Stored cross-site scripting in Epsilon Web Manufactory WP Fast Total Search 1.68.232 and earlier allows remote attackers to execute script. Public advisories do not identify the affected input, storage location, rendering function, or missing neutralization operation. Exploitation requires an attacker-supplied value to be stored and later rendered in another user's browser, so user interaction gates the impact.
