This critical-severity CVE scores 9.9 under NVD CVSS v3. EPSS exploit probability: 1.1%, top 39% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Knowage is an open source analytics and business intelligence suite. Starting in the 6.x.x branch and prior to version 8.1.8, the endpoint /knowage/restful-services/dossier/importTemplateFile allows authenticated users to upload template file on the server, but does not need any authorization to be reached. When the JSP file is uploaded, the attacker just needs to connect to /knowageqbeengine/foo.jsp to gain code execution on the server. By exploiting this vulnerability, an attacker with low privileges can upload a JSP file to the knowageqbeengine directory and gain code execution capability on the server. This issue has been patched in Knowage version 8.1.8.
