Overview
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the syndication process. An attacker can cause the server to fetch arbitrary URLs, potentially targeting internal hosts and ports, reading back fetched feed content in the rendered page, and causing feed enclosures to be downloaded into the files directory by supplying crafted input to the content parameter of the render handler.
