How severe is GHSA-6x49-w35h-wqrj?

GHSA-6x49-w35h-wqrj has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which packages are affected by GHSA-6x49-w35h-wqrj?

GHSA-6x49-w35h-wqrj affects the following packages: org.apache.dubbo:dubbo (Maven), org.apache.dubbo:dubbo (Maven). Ecosystems affected: Maven.

How do I fix GHSA-6x49-w35h-wqrj?

Update org.apache.dubbo:dubbo to 3.1.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6x49-w35h-wqrj is resolved across your whole dependency graph.

How do I detect GHSA-6x49-w35h-wqrj in my Maven dependencies?

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

How do I mitigate GHSA-6x49-w35h-wqrj if there is no patch (or I can't update yet)?

Do not deserialise data from untrusted sources: where the format allows it, restrict deserialisation to an explicit allowlist of expected types, and prefer a data-only format (JSON, Protobuf) over one that can reconstruct arbitrary objects until you can upgrade.

Is GHSA-6x49-w35h-wqrj actively exploited in the wild?

No public exploit code has been indexed for GHSA-6x49-w35h-wqrj 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-6x49-w35h-wqrj?

GHSA-6x49-w35h-wqrj has an EPSS (Exploit Prediction Scoring System) score of 7.4%, placing it in the 94th 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-6x49-w35h-wqrj?

GHSA-6x49-w35h-wqrj is classified as Deserialization of Untrusted Data (CWE-502). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was GHSA-6x49-w35h-wqrj published, and has it been updated?

GHSA-6x49-w35h-wqrj was published on December 15, 2023 and was last updated on February 13, 2025. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
