EchelonGraph scoreLOW confidence

This critical-severity CVE scores 9.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). 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).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

In the query parser in OpenStack Vitrage before 12.0.1, 13.0.0, 14.0.0, and 15.0.0, a user allowed to access the Vitrage API may trigger code execution on the Vitrage service host as the user the Vitrage service runs under. This may result in unauthorized access to the host and further compromise of the Vitrage service. All deployments exposing the Vitrage API are affected. This occurs in _create_query_function in vitrage/graph/query.py.
