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

**Signal:** Critical, preconditions apply. Severe if exploited, but exploitation needs conditions that may not apply to you. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- 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.

## Affected packages

- PyPI `vitrage` >= 15.0.0.0rc1, < 15.0.1 → fixed: 15.0.1
- PyPI `vitrage` >= 14.0.0.0rc1, < 14.0.1 → fixed: 14.0.1
- PyPI `vitrage` >= 13.0.0.0rc1, < 13.0.1 → fixed: 13.0.1
- PyPI `vitrage` < 12.0.1 → fixed: 12.0.1

## Affected products (CVE record)

- OpenStack Vitrage: < 12.0.1, 13.0.0, 14.0.0, 15.0.0

## Severity

- mitre CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.1 `CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation none , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.84% probability of exploitation activity in the next 30 days; percentile 57.
