EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description
Impact
It is possible to make the entire Cube API unavailable by submitting a specially crafted request to a Cube API endpoint.
Patches
The issue has been patched in the v0.34.34 and it's recommended that all users exposing Cube APIs to the public internet upgrade to the latest version to prevent service disruption.
Workarounds
There are currently no workaround for older versions, and the recommendation is to upgrade.
References
The issue was reported by y0d3n in our Community Slack and has been promptly patched in the recent update.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @cubejs-backend/api-gateway. 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.
Fix
Update @cubejs-backend/api-gateway to 0.34.34 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9759-3276-g2pm is resolved across your whole dependency graph.
Workarounds
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 O3 protects you
O3 pinpoints whether GHSA-9759-3276-g2pm is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-9759-3276-g2pm. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-9759-3276-g2pm in your dependencies?
O3 detects GHSA-9759-3276-g2pm across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
