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.
WWBN AVideo 12.4 至 29.2.0 版本存在一个存储型跨站脚本（XSS）漏洞，允许经过身份验证的上传者通过在视频标题中提交双重编码的实体注入 HTML。由于 safeString() 函数在解码实体之前会先剥离标签，并且该函数在 setTitle() 和 save() 方法中被调用了两次，攻击者可以存储能够在“趋势页面”、“画廊页面”、“嵌入页面”以及“播放列表页面”中执行的恶意标记。

WWBN AVideo 12.4 through 29.2.0 Stored XSS via Double-Encoded Video Title
Source: CVE Program / CVE List V5
Vulnerability Description
WWBN AVideo 12.4 through 29.2.0 contains a stored cross-site scripting vulnerability that allows authenticated uploaders to inject HTML by submitting doubly-encoded entities in video titles. Because safeString() strips tags before decoding entities and runs twice via setTitle() and save(), attackers can store markup that executes in trending, gallery, embed, and playlist pages.
