How severe is GHSA-qffm-gf3j-6mvg?

No CVSS score has been assigned to GHSA-qffm-gf3j-6mvg yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-qffm-gf3j-6mvg?

GHSA-qffm-gf3j-6mvg affects the following packages: org.apache.cassandra:cassandra-all (Maven), org.apache.cassandra:cassandra-all (Maven), org.apache.cassandra:cassandra-all (Maven). Ecosystems affected: Maven.

How do I fix GHSA-qffm-gf3j-6mvg?

Update org.apache.cassandra:cassandra-all to 4.0.20 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-qffm-gf3j-6mvg is resolved across your whole dependency graph.

How do I detect GHSA-qffm-gf3j-6mvg in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.cassandra:cassandra-all, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-qffm-gf3j-6mvg if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is GHSA-qffm-gf3j-6mvg actively exploited in the wild?

No public exploit code has been indexed for GHSA-qffm-gf3j-6mvg 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-qffm-gf3j-6mvg?

GHSA-qffm-gf3j-6mvg has an EPSS (Exploit Prediction Scoring System) score of 0.7%, placing it in the 49th 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-qffm-gf3j-6mvg?
