How severe is GHSA-pqwh-c2f3-vxmq?

No CVSS score has been assigned to GHSA-pqwh-c2f3-vxmq yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-pqwh-c2f3-vxmq?

GHSA-pqwh-c2f3-vxmq affects the following packages: github.com/vapor/vapor (SwiftURL). Ecosystems affected: SwiftURL.

How do I fix GHSA-pqwh-c2f3-vxmq?

Update github.com/vapor/vapor to 4.47.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-pqwh-c2f3-vxmq is resolved across your whole dependency graph.

How do I detect GHSA-pqwh-c2f3-vxmq in my SwiftURL dependencies?

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

How do I mitigate GHSA-pqwh-c2f3-vxmq 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-pqwh-c2f3-vxmq actively exploited in the wild?

No public exploit code has been indexed for GHSA-pqwh-c2f3-vxmq 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-pqwh-c2f3-vxmq?

GHSA-pqwh-c2f3-vxmq has an EPSS (Exploit Prediction Scoring System) score of 1.2%, placing it in the 68th 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-pqwh-c2f3-vxmq?

GHSA-pqwh-c2f3-vxmq 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-pqwh-c2f3-vxmq published, and has it been updated?

GHSA-pqwh-c2f3-vxmq was published on June 9, 2023 and was last updated on July 8, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Real-World Exposure

1 pkg affected

📦github.com/vapor/vapor

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects SwiftURL packages — download data is not available via public APIs for these ecosystems.

Description

Impact

A bug in the Data.init(base32Encoded:) function opens up the potential for exposing server memory and/or crashing the server (Denial of Service) for applications where untrusted data can end up in said function. Vapor does not currently use this function itself so this only impact applications that use the impacted function directly or through other dependencies.

Patches

This issue has been patched in 4.47.2.

Workarounds

Use an alternative to Vapor's built-in Data.init(base32Encoded:).
