CVE-2024-8790Network attack vector

Reflected XSS via unescaped query-argument URL

Published Oct 18, 2024 · Updated Apr 8, 2026

Reflected XSS in ThemeInWP Social Share With Floating Bar 1.0.3 and earlier allows remote attackers to execute scripts via crafted links. The settings-page code passes a URL through add_query_arg and writes the result into an HTML link without context-appropriate output escaping. Exploitation is unauthenticated but requires a victim to follow the crafted link, after which the injected script runs in that victim's browser session.
