Security readout for executives and security teams
Plain-English summary
GLPI versions before 10.0.1 allow a logged-in user to store HTML in their username that can execute as cross-site scripting in Kanban views. This is not a system takeover, but it can expose data or alter actions for users who view affected boards. Upgrade is the vendor-recommended resolution.
Executive priority
Schedule remediation in the normal vulnerability cycle, faster for internet-facing or broadly shared GLPI deployments. The issue can affect user trust and data confidentiality, but available evidence supports moderate urgency rather than emergency response.
Technical view
CVE-2022-24876 is stored XSS in GLPI Kanban affecting glpi-project GLPI versions below 10.0.1. The attack vector is network-accessible, low complexity, requires low privileges, and requires another user to interact with the affected Kanban view. CVSS 3.1 is 5.4 with low confidentiality and integrity impact.
Likely exposure
Exposure is limited to organizations running GLPI before 10.0.1 and using Kanban views for Projects, Tickets, Changes, or Problems. Risk is higher where many low-privileged or external users can set profile names and where administrators routinely view shared Kanban boards.
Exploitation context
The source bundle does not show CISA KEV listing or known active exploitation. Exploitation requires an authenticated user to inject HTML into their username and another user to view the affected Kanban context. Treat as plausible insider or compromised-account abuse, not confirmed widespread exploitation.
Researcher notes
The affected component is GLPI Kanban rendering of user names. The CVSS vector indicates authenticated, low-complexity stored XSS with user interaction and changed scope. Sources state no workarounds; avoid assuming sanitization rules or backportable fixes beyond vendor guidance.
Mitigation direction
- Upgrade GLPI to version 10.0.1 or later.
- Check vendor advisory before applying compensating controls.
- Limit who can create or modify GLPI user names until upgraded.
- Review suspicious GLPI usernames containing HTML-like markup.
- Prioritize systems exposed to broad user populations or third parties.
Validation and detection
- Inventory GLPI instances and confirm installed versions.
- Verify whether each instance is below 10.0.1.
- Confirm Kanban views are enabled or used for tracked objects.
- Review user profile names for unexpected markup.
- After upgrade, confirm GLPI reports version 10.0.1 or later.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
