GHSA-pqwh-c2f3-vxmq
GHSA-pqwh-c2f3-vxmq is a Deserialization of Untrusted Data vulnerability in github.com/vapor/vapor. O3 Security confirms whether GHSA-pqwh-c2f3-vxmq is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Untrusted data fed into `Data.init(base32Encoded:)` can result in exposing server memory and/or crash
Real-World Exposure
github.com/vapor/vaporReal-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:).

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/vapor/vapor. 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 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.
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-pqwh-c2f3-vxmq 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-pqwh-c2f3-vxmq. 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-pqwh-c2f3-vxmq in your dependencies?
O3 detects GHSA-pqwh-c2f3-vxmq across SwiftURL dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
