CVE-2023-28636Network attack vector

Stored script execution via malicious external link

Published Apr 5, 2023 · Updated Feb 10, 2025

Stored XSS in GLPI 0.60 through 9.5.12 and 10.0.0 through 10.0.6 allows remote authenticated users to inject script via external links. The maintainer identifies the external-link creation feature but has not disclosed which field or rendering operation fails to neutralize the stored value. Administrator privileges are required to store the link, and another user must render it; script execution occurs in that user's browser and can expose data available to that session.
