How severe is GHSA-gwvq-rgqf-993f?

GHSA-gwvq-rgqf-993f has a CVSS score of 6/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-gwvq-rgqf-993f?

GHSA-gwvq-rgqf-993f affects the following packages: python-keystoneclient (PyPI). Ecosystems affected: PyPI.

How do I fix GHSA-gwvq-rgqf-993f?

Update python-keystoneclient to 0.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-gwvq-rgqf-993f is resolved across your whole dependency graph.

How do I detect GHSA-gwvq-rgqf-993f in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for python-keystoneclient. 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-gwvq-rgqf-993f 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-gwvq-rgqf-993f?

O3 pinpoints whether GHSA-gwvq-rgqf-993f 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-gwvq-rgqf-993f actively exploited in the wild?

No public exploit code has been indexed for GHSA-gwvq-rgqf-993f 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-gwvq-rgqf-993f?

GHSA-gwvq-rgqf-993f has an EPSS (Exploit Prediction Scoring System) score of 1.1%, placing it in the 61th 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.

When was GHSA-gwvq-rgqf-993f published, and has it been updated?

GHSA-gwvq-rgqf-993f was published on May 17, 2022 and was last updated on October 25, 2024. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

A context confusion vulnerability was identified in Keystone auth_token middleware (shipped in python-keystoneclient) before 0.7.0. By doing repeated requests, with sufficient load on the target system, an authenticated user may in certain situations assume another authenticated user's complete identity and multi-tenant authorizations, potentially resulting in a privilege escalation. Note that it is related to a bad interaction between eventlet and python-memcached that should be avoided if the calling process already monkey-patches "thread" to use eventlet. Only keystone middleware setups using auth_token with memcache are vulnerable.
