CVE-2026-100630— AVideo Stored XSS via HTML Entity Bypass in trailer1 Field

Quick assessment

Affected
WWBN AVideo
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

AVideo 中存在一个存储型跨站脚本（XSS）漏洞，该漏洞发生在视频预告片（video trailer）字段中。当该字段的值被未经验证和清理地嵌入到内联的 onclick JavaScript 字符串中时，会导致安全风险。拥有视频上传权限的攻击者可以存储经过 HTML 实体编码的有效负载，这些有效负载能够绕过 isValidURL() 验证函数，并被浏览器解码后跳出当前的 JavaScript 字符串上下文，从而在任意访问者（包括管理员）的会话中执行任意代码。
