CVE-2026-61564— AVideo-Encoder: unauthenticated installer PHP code injection

Quick assessment

Affected
WWBN AVideo-Encoder
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 是一个视频分享平台。在 8.1.0 版本之前，未经验证的安装程序端点 会将请求参数（包括 ）直接插值到单引号 PHP 字符串字面量中，以生成 文件，且未进行转义处理。攻击者可以终止该字符串字面量并注入 PHP 代码；当生成的文件被直接请求加载时，该代码将以 Web 服务器用户的身份执行。利用此漏洞需要 文件不存在（例如在首次部署时，或该文件被删除/移动后）；若该文件已存在，则此端点将被阻止。攻击者提供的 必须包含 ，并且使用 、 和 参数建立的数据库连接必须成功；但攻击者可将这些参数指向其控制的数据库

Vulnerability Title
AVideo-Encoder: unauthenticated installer PHP code injection
Source: CVE Program / CVE List V5
Vulnerability Description
AVideo is a video-sharing Platform. Prior to 8.1.0, the unauthenticated installer endpoint `install/checkConfiguration.php` assembles `videos/configuration.php` by interpolating request parameters, including `webSiteRootURL`, into single-quoted PHP string literals without escaping. An attacker can terminate a literal and inject PHP that executes as the web-server user when the generated, directly requestable file is loaded. Exploitation requires `videos/configuration.php` to be absent, as on every fresh deployment or after the file is removed or moved; an existing file blocks this endpoint. The supplied `systemRootPath` must contain index.php and a connection using `databaseHost`, `databaseUser`, and `databasePass` must succeed, but the attacker can point those parameters to their own database server and needs no target credentials. The write location is also derived from `systemRootPath` without a base-directory constraint. This permits arbitrary command execution, reading and overwriting files owned by the web-server user, persistent PHP code, and control over stored database connection settings. The endpoint additionally interpolates request values into streamer and configuration INSERT statements, creating a secondary SQL-injection sink. This issue is fixed in version 8.1.0.
