Omnispace Agora Project 版本低于 26.10.0 存在一个存储型跨站脚本（XSS）漏洞。该漏洞允许已认证用户通过上传文件名中嵌入 HTML 或脚本标记的文件来注入恶意脚本，从而绕过 paramFilter 过滤器，因为上传文件的文件名通过 $_FILES 变量传入，而非 $_GET 或 $_POST。攻击者可上传具有构造文件名的文件（例如包含 SVG onload 有效载荷的文件），使未经过清理的文件名被存储，并在后续对其他用户展示时触发浏览器中的恶意脚本执行。

Vulnerability Title
Omnispace Agora Project < 26.10.0 Stored XSS via Uploaded File Name
Source: CVE Program / CVE List V5
Vulnerability Description
Omnispace Agora Project before 26.10.0 contains a stored cross-site scripting vulnerability that allows authenticated users to inject malicious script by uploading a file with HTML/script markup embedded in its filename, which bypasses the paramFilter since uploaded-file names arrive through $_FILES rather than $_GET/$_POST. Attackers can upload a file with a crafted name such as an SVG onload payload to have the unsanitized filename stored and later rendered to other users, resulting in script execution in their browsers.
