Stored XSS via allowed stylesheet links
Published Apr 21, 2022 · Updated Apr 23, 2025
Stored cross-site scripting in GLPI before 10.0.0 allows remote authenticated users to inject stylesheet content into rendered pages. Toolbox::getHtmLawedSafeConfig failed to forbid link elements, so stored ticket follow-ups or login messages could make browsers load an attacker-selected stylesheet. An account able to add a ticket follow-up or configure a login message is required, and the consequence occurs when another user views the stored content.
