EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.4 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.5%, top 56% 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).

Improper authorization in the ToolGroupResource and RoleAjax REST/DWR endpoints in dotCMS dotCMS 21.02 through 26.06.22-03 on all platforms allows a low-privileged authenticated backend user to self-assign the administrative layout and self-grant the CMS Administrator role, then achieve remote code execution via a crafted OSGi bundle upload whose BundleActivator executes arbitrary shell commands.
