SimplePie through 1.9.0 Local File Read via file:// Redirect

SimplePie through 1.9.0 contains a local file read vulnerability that allows malicious feed servers to read server files by supplying file:// URLs in redirects or autodiscovery links. Attackers can return a Location header or feed link pointing to a file:// path, causing file_get_contents() to read files accessible to the web server process.
