Which packages are affected by GHSA-8xwf-cr4r-856r?

GHSA-8xwf-cr4r-856r affects the following packages: vitrage (PyPI), vitrage (PyPI), vitrage (PyPI), vitrage (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-8xwf-cr4r-856r?

Update vitrage to 15.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8xwf-cr4r-856r is resolved across your whole dependency graph.

How do I detect GHSA-8xwf-cr4r-856r in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for vitrage. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate GHSA-8xwf-cr4r-856r if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against GHSA-8xwf-cr4r-856r?

O3 pinpoints whether GHSA-8xwf-cr4r-856r is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is GHSA-8xwf-cr4r-856r actively exploited in the wild?

No public exploit code has been indexed for GHSA-8xwf-cr4r-856r yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-8xwf-cr4r-856r?

GHSA-8xwf-cr4r-856r has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 51th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-8xwf-cr4r-856r?

GHSA-8xwf-cr4r-856r is classified as CWE-95 (CWE-95). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-8xwf-cr4r-856r published, and has it been updated?

GHSA-8xwf-cr4r-856r was published on February 27, 2026 and was last updated on March 5, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.

Description

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.
