Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In GLPI from version 9.1 and before version 9.4.6, any API user with READ right on User itemtype will have access to full list of users when querying apirest.php/User. The response contains: - All api_tokens which can be used to do privileges escalations or read/update/delete data normally non accessible to the current user. - All personal_tokens can display another users planning. Exploiting this vulnerability requires the api to be enabled, a technician account. It can be mitigated by adding an application token. This is fixed in version 9.4.6.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

GLPI REST API (apirest.php) exposes all users' API tokens and personal tokens to any authenticated user with READ rights on User itemtype, enabling privilege escalation and unauthorized access to planning data. The vulnerability exists in versions 9.1 through 9.4.5 and requires the API to be enabled with a technician account.

MitigationUpgrade to GLPI version 9.4.6 or later. Alternatively, adding an application token can mitigate the risk until upgrade is possible.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify GLPI version
    Locate the GLPI installation directory and check the version file (typically version.php or similar) or access the GLPI login page footer which displays the version number
    Affected if The installed version is 9.1 through 9.4.5 (inclusive)
  2. Confirm REST API is enabled
    Check if the file apirest.php exists in the /ajax/ or /front/ directory of the GLPI installation and is accessible via HTTP
    Affected if The REST API endpoint (apirest.php) exists and responds to requests
  3. Verify API authentication is configured
    Attempt to authenticate to the REST API using a technician account's credentials (username and password) to obtain a session token
    Affected if A valid technician account can successfully authenticate to the REST API and receive a session token
  4. Check User itemtype read access
    Examine the profile permissions for the authenticated API user to determine if they have READ rights on the User itemtype
    Affected if The API-authenticated user has READ or higher permission on User objects in their profile

A user is affected if they run GLPI versions 9.1-9.4.5 with the REST API enabled and a technician account that has READ access to User items, allowing that account to view all users' API tokens.
