CVE-2025-59358
HIGHCVE-2025-59358 is a high-severity (CVSS 7.5) Missing Authentication vulnerability in github.com/chaos-mesh/chaos-mesh. O3 Security confirms whether CVE-2025-59358 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Denial of Service via Unauthorized Access to Chaos Mesh debugging server
Blast Radius
github.com/chaos-mesh/chaos-meshReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.
Description
The Chaos Controller Manager in Chaos Mesh exposes a GraphQL debugging server without authentication to the entire Kubernetes cluster, which provides an API to kill arbitrary processes in any Kubernetes pod, leading to cluster-wide denial of service.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 🐹Go | github.com/chaos-mesh/chaos-mesh | all versions | 2.7.3 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/chaos-mesh/chaos-mesh. 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/chaos-mesh/chaos-mesh to 2.7.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-59358 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 CVE-2025-59358 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 CVE-2025-59358. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2025-59358 in your dependencies?
O3 detects CVE-2025-59358 across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
