CVE-2026-89247Public exploitNetwork attack vectorHinoki check available

Ad injection via unescaped VMAP attributes

Published Sep 11, 2026 · Updated Sep 15, 2026

XML injection in WWBN AVideo at commit c3edcc274c389816d434acadac07ee78eaf330c1 and earlier allows remote attackers to inject video ads. VMAP.php writes base64- and JSON-decoded vmaps timeOffset and idTag values into XML attributes without encoding, allowing injected nodes. The AD_Server plugin must be enabled, and a victim must open the crafted VMAP URL or a video page that uses it; the resulting player session fetches attacker-supplied ad URLs.
