CVE-2025-21627Network attack vector

Script execution via reflected search-page input

Published Feb 25, 2025 · Updated Feb 25, 2025

Reflected XSS in the search page in GLPI before 10.0.18 allows remote attackers to execute script via a crafted link. The GLPI Project advisory does not identify the affected request parameter or the output operation that reflects its value without sufficient neutralization. Exploitation requires a user to follow the malicious link; anonymous ticket creation makes the page reachable without authentication, and injected script runs in the visitor's browser context.
