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是WWBN团队的一个由PHP编写的视频平台建站系统。 WWBN AVideo 26.0之前版本存在代码问题漏洞，该漏洞源于Scheduler插件的run函数未对管理员可配置的callbackURL进行SSRF安全检查，可能导致管理员配置内部网络回调URL，对云基础设施元数据服务或内部API进行服务端请求伪造攻击。

Vulnerability Title
AVideo has SSRF in Scheduler Plugin via callbackURL Missing `isSSRFSafeURL()` Validation
Source: CVE Program / CVE List V5
Vulnerability Description
WWBN AVideo is an open source video platform. Prior to version 26.0, the Scheduler plugin's `run()` function in `plugin/Scheduler/Scheduler.php` calls `url_get_contents()` with an admin-configurable `callbackURL` that is validated only by `isValidURL()` (URL format check). Unlike other AVideo endpoints that were recently patched for SSRF (GHSA-9x67-f2v7-63rw, GHSA-h39h-7cvg-q7j6), the Scheduler's callback URL is never passed through `isSSRFSafeURL()`, which blocks requests to RFC-1918 private addresses, loopback, and cloud metadata endpoints. An admin can configure a scheduled task with an internal network `callbackURL` to perform SSRF against cloud infrastructure metadata services or internal APIs not otherwise reachable from the internet. Version 26.0 contains a patch for the issue.
