GHSA-rqrc-8q8f-cp9c
HIGHGHSA-rqrc-8q8f-cp9c is a high-severity (CVSS 7.5) Unrestricted File Upload vulnerability in Bond.Core.CSharp. O3 Security confirms whether GHSA-rqrc-8q8f-cp9c is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Infinite loop in .Net Bond
Blast Radius
Bond.Core.CSharpReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects NuGet packages — download data is not available via public APIs for these ecosystems.
Description
A denial of service vulnerability exists when the .NET implementation of Bond improperly parses input, aka 'Bond Denial of Service Vulnerability'. Handling of large container lengths that could cause an infinite loop when deserializing some payloads.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| .NETNuGet | Bond.Core.CSharp | ≥ 3.0.0&&< 9.0.1 | 9.0.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for Bond.Core.CSharp. 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 Bond.Core.CSharp to 9.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-rqrc-8q8f-cp9c 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-rqrc-8q8f-cp9c 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-rqrc-8q8f-cp9c. 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-rqrc-8q8f-cp9c in your dependencies?
O3 detects GHSA-rqrc-8q8f-cp9c across NuGet dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
