CVE-2023-28633Network attack vector

Authenticated blind SSRF via RSS autodiscovery

Published Apr 5, 2023 · Updated Feb 10, 2025

SSRF in GLPI 0.84 through 9.5.12 and 10.0.0 through 10.0.6 allows remote authenticated users to trigger server-side requests. When a configured URL fails as a feed, RSSFeed::showDiscoveredFeeds performs RSS autodiscovery and retrieves discovered URLs without safety checks. A low-privileged account with RSS-feed access can cause blind requests from the GLPI server and infer limited response information.
