YesWiki before 4.7.0 contains an unauthenticated server-side request forgery vulnerability that allows remote attackers to fetch arbitrary URLs by supplying [[|URL]] wiki syntax to the render handler. Attackers can pass the syntax in the content parameter of the page render handler to reach internal hosts and ports and read their responses.
