原文摘录

摘自原文(3464 字符中的一小部分)
I found a Server-Side Request Forgery vulnerability in the game export functionality. An attacker can make the Lichess server send HTTP requests to arbitrary URLs by manipulating the `players` parameter. This works on public endpoints that don't require any authentication
原文中的代码
val config = GameApiV2.OneConfig(
  format = GameApiV2.Format.byRequest,
  imported = getBool("imported"),
  flags = requestPgnFlags(extended = true),
  playerFile = get("players")  // User input taken directly
)
