Operationally, ranked in the top 10.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
GLPI, an open-source IT asset and service management platform, contains an improper access control flaw in its Kanban feature. Any authenticated user, regardless of assigned profile, can manipulate the component to modify arbitrary user fields, ultimately allowing account takeover. The issue is tracked as CVE-2023-41326 with a CVSS 3.1 score of 8.1 and is also associated with CWE-269.
An attacker who already possesses valid credentials can exploit the Kanban interface to alter another user’s account details, including password or email fields, thereby hijacking the target account without further interaction from the victim. The attack requires only low-privilege network access and succeeds against any profile because the Kanban endpoint fails to enforce proper authorization checks on user-field modifications.
The project’s security advisories direct administrators to upgrade to GLPI 10.0.10, the release that contains the fix; no workarounds are documented. The associated EPSS score rose from lower values to a peak of 0.0670 before receding to its current level of 0.0435, indicating a modest but noticeable increase in exploitation interest after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Policy addresses roles, responsibilities, and privilege management to prevent improper privilege assignments.
Access supervision ensures privileges are assigned and managed without improper escalation or retention.
Assigning group/role memberships and access authorizations (privileges) while reviewing accounts addresses improper privilege management.
Enforces proper privilege management by requiring all decisions through the verified reference monitor.
By mandating division of duties across roles, the control enforces proper privilege management and prevents a single entity from controlling an entire sensitive process.
Implements core proper privilege management by restricting to only required rights.
Policy requires training on privilege management and least privilege, making it harder to exploit improper privilege management weaknesses.
Training covers proper privilege management practices, making incorrect privilege assignments less likely.
