CVE-2025-23809Network attack vector

Unauthenticated script execution via reflected input

Published Jan 22, 2025 · Updated Apr 28, 2026

Reflected XSS in Sunil Nanda Blue Wrench Video Widget 2.1.0 and earlier allows remote attackers to execute scripts via crafted input. Public advisories attribute the flaw to insufficient input sanitization and output escaping but do not identify the affected parameter or code path. Exploitation is unauthenticated but requires a victim to follow a crafted link or perform an equivalent attacker-induced action, exposing the victim's browser context to injected script.
