CVE-2026-28370: OpenStack Vitrage: Unauthorized Access to the Host can Lead to Eval Injection
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.

Should you act?
Critical, preconditions apply
Severe if exploited, but exploitation needs conditions that may not apply to you. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.
- No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 0.8%, percentile 57: FIRST’s model estimates a 0.8% chance of exploitation activity in the next 30 days, higher than 57% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
- Needs an account (high (admin)). Exposure depends on who can log in.
- Only applies if your dependency tree includes
vitrage(PyPI) >= 15.0.0.0rc1, < 15.0.1, fixed in 15.0.1;vitrage(PyPI) >= 14.0.0.0rc1, < 14.0.1, fixed in 14.0.1;vitrage(PyPI) >= 13.0.0.0rc1, < 13.0.1, fixed in 13.0.1;vitrage(PyPI) < 12.0.1, fixed in 12.0.1. Check your lockfile, including transitive dependencies.
What it is
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 createqueryfunction in vitrage/graph/query.py.
