CVE-2022-39276Network attack vector

Authenticated internal resource probing via unchecked redirects

Published Nov 3, 2022 · Updated Apr 22, 2025

SSRF in GLPI before 10.0.4 allows remote authenticated users to make server-side requests through RSS feeds or external calendars. When a remote resource returns an HTTP redirect, the RSS-feed and planning fetch path follows the target without applying the administrator-defined URL allowlist. Low-privileged access and a redirecting endpoint are required, and the blind response channel limits the reported impact to indirect disclosure of reachable resources.
