How severe is GHSA-8cw6-5qvp-q3wj?

GHSA-8cw6-5qvp-q3wj has a CVSS score of 5.4/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by GHSA-8cw6-5qvp-q3wj?

GHSA-8cw6-5qvp-q3wj affects the following packages: org.apache.spark:spark-core_2.10 (Maven), org.apache.spark:spark-core_2.10 (Maven), org.apache.spark:spark-core_2.11 (Maven), org.apache.spark:spark-core_2.11 (Maven), org.apache.spark:spark-core_2.11 (Maven). Ecosystems affected: Maven.

How do I fix GHSA-8cw6-5qvp-q3wj?

Update org.apache.spark:spark-core_2.10 to 2.1.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-8cw6-5qvp-q3wj is resolved across your whole dependency graph.

How do I detect GHSA-8cw6-5qvp-q3wj in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.spark:spark-core_2.10, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-8cw6-5qvp-q3wj if there is no patch (or I can't update yet)?

Assume what was exposed is already known: rotate any credential, token or key that the affected component could return, restrict the endpoint to callers that genuinely need it, and strip sensitive fields from responses and error output at the boundary rather than relying on the client not to read them.

Is GHSA-8cw6-5qvp-q3wj actively exploited in the wild?

No public exploit code has been indexed for GHSA-8cw6-5qvp-q3wj 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-8cw6-5qvp-q3wj?

GHSA-8cw6-5qvp-q3wj has an EPSS (Exploit Prediction Scoring System) score of 5.3%, placing it in the 93th 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-8cw6-5qvp-q3wj?

GHSA-8cw6-5qvp-q3wj is classified as Information Exposure (CWE-200). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Is there exploit tooling available for GHSA-8cw6-5qvp-q3wj?

A Nuclei detection template exists for GHSA-8cw6-5qvp-q3wj, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was GHSA-8cw6-5qvp-q3wj published, and has it been updated?

GHSA-8cw6-5qvp-q3wj was published on March 14, 2019 and was last updated on September 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

In Apache Spark 2.1.0 to 2.1.2, 2.2.0 to 2.2.1, and 2.3.0, it's possible for a malicious user to construct a URL pointing to a Spark cluster's UI's job and stage info pages, and if a user can be tricked into accessing the URL, can be used to cause script to execute and expose information from the user's view of the Spark UI. While some browsers like recent versions of Chrome and Safari are able to block this type of attack, current versions of Firefox (and possibly others) do not.
