The impact is limited to systems where the GLPI installation is accessible to administrators, as an attacker must authenticate with administrative rights to trigger the template injection. The software is available through the GLPI project website and open\u2011source repositories, so many corporate and public deployments remain affected.", "description_and_impact": "GLPI is a widely used asset and IT management platform that suffered a Server\u2011Side Template Injection vulnerability in templating logic, allowing an authenticated administrator to craft input that is compiled twice by the template engine. The double\u2011compilation flaw makes it possible to inject arbitrary code, effectively bypassing the web application\u2019s input filtering.

The vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog, further indicating that it has not yet been widely abused by attackers. That said, if an attacker gains admin credentials or otherwise compromises an administrator\u2019s session, the attack vector becomes a straightforward web\u2011based exploitation and can provide full control of the underlying server."}}}}, "created": "2026-04-06T20:14:28.642015+00:00", "updated": "2026-04-08T19:50:51.896900+00:00", "vendors": ["glpi-project", "glpi-project$PRODUCT$glpi"]}
