CVE-2026-82646: WWBN AVideo Unauthenticated Reflected XSS via url2Embed.json.php
WWBN AVideo contains an unauthenticated reflected cross-site scripting vulnerability in the url2Embed.json.php endpoint that allows attackers to inject malicious scripts by supplying URLs with HTML metacharacters. Attackers can mint an encrypted evideo payload containing unescaped markup, then deliver it as a legitimate-looking link on the site's own domain to execute JavaScript in victims' sessions and steal cookies or CSRF tokens.

Frequently Asked Questions
Who can exploit this issue?
An attacker does not need to authenticate. They need to craft an encrypted evideo payload containing unescaped HTML markup and persuade a victim to open a link on the affected site's own domain.
What is required for impact on a victim?
Victim interaction is required: the victim must visit the attacker-supplied link. The injected JavaScript executes in the victim's session and may expose cookies or CSRF tokens.
Which endpoint should be investigated for exposure?
Investigate the url2Embed.json.php endpoint, particularly whether it processes encrypted evideo payloads that can contain URLs with HTML metacharacters. The provided information does not identify affected versions or a fixed release.
