CVE-2026-63156Network attack vectorHinoki check available

Browser script execution via visioUrl attribute injection

Published Oct 13, 2026 · Updated Oct 13, 2026

Reflected XSS in Agora-Project before 26.10.0 allows remote attackers to execute browser JavaScript via a crafted visioUrl parameter. The parameter filter in app/Common/Req.php skips URL sanitization for visioUrl and URL-decodes its value after filtering, allowing injected attributes to escape their HTML context. No attacker authentication is required, but a victim must open the crafted URL; execution occurs in the victim's browser, not on the server.
