Internal resource disclosure via unvalidated HTTPS fetch
Published Apr 2, 2021 · Updated Aug 3, 2024
Server-side request forgery in MagpieRSS 0.72 allows remote attackers to read internal HTTPS resources through exposed example scripts. The magpie_debug.php and magpie_simple.php scripts pass an attacker-controlled RSS URL to Snoopy::_httpsrequest, which executes curl for the supplied URI without restricting the destination host. The scripts must be web-reachable and curl must be executable; the reported consequence is disclosure of resources reachable from the server, not modification or service interruption.
