Hello Sam,
prior versions of Wazuh run vulnerability detection scans based on an interval and ignore settings. This means that every time a new scan happens (and the ignore setting is surpassed) you will see alerts related to a vulnerability that already triggered an alert scans ago. To put it in other words, Wazuh wasn't able to show state information related to vulnerability detection data about an endpoint at a given point in time.
In Wazuh 4.3.x, the vulnerability detection panel shows the current state of an agent while offering historic information about a CVE in that particular endpoint when you click on the detailed view of that CVE:
You still can get alert information related to vulnerability detection across the whole environment by going to Security Events (or creating a custom dashboard) and applying a filter for rule.groups: vulnerability-detector.
Hope that helps!
