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
Wazuh is a security detection, visibility, and compliance open source project. In versions 4.4.0 and 4.4.1, it is possible to get the Wazuh API administrator key used by the Dashboard using the browser development tools. This allows a logged user to the dashboard to become administrator of the API, even if their dashboard role is not. Version 4.4.2 contains a fix. There are no known workarounds.

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
How this class of weakness works · CWE-639

The application uses a user-supplied identifier to look up a record without checking that the requester actually owns it, so changing the identifier in a request returns someone else's data. This is the classic insecure-direct-object-reference — the change-the-ID-in-the-URL bug. Remediation is authorizing every object access against the acting user, not merely confirming they are logged in.
