Summary

internal/api/audit.go:12, handleGetAuditLog does no admin check. The route is bearer-auth gated only; any operator API key returns the full audit log via store.ListAuditEntries (up to limit=1000). This includes cross-tenant actor names, host/CA/operator IDs, action timestamps, and masked-IP entries from rate-limit refusals, enough surface for a tenant to enumerate the server's activity, infer staffing patterns, or identify high-value targets. Affected All released versions up to v0.3.1. Reproducer Suggested fix Two options, either acceptable: if !actorIsAdmin(ctx) { 403 }, strictest; matches the "operator management is admin-only" stance. Scope to actor: filter store.ListAuditEntries by actor.Username plus a subquery of CA IDs the actor owns. Operators see their own audit entries plus entries against their CA's resources. Recommend option 1 unless the UI needs per-operator audit views. Suggested patch Verified locally: go vet, go test -race -count=1 ./..., golangci-lint v2.12 all clean.

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter instead of chasing every advisory.

Kodem's runtime-powered SCA identifies whether CVE-2026-47726 is reachable in your applications. Explore open-source security for your team.

Frequently asked questions about CVE-2026-47726

What is CVE-2026-47726?

CVE-2026-47726 is a high-severity security vulnerability in github.com/juev/nebula-mesh (go), affecting versions <= 0.3.1. It is fixed in 0.3.2.

Which versions of github.com/juev/nebula-mesh are affected by CVE-2026-47726?

github.com/juev/nebula-mesh (go) versions <= 0.3.1 is affected.

Is there a fix for CVE-2026-47726?

Yes. CVE-2026-47726 is fixed in 0.3.2. Upgrade to this version or later.

Is CVE-2026-47726 exploitable, and should I be worried?

Whether CVE-2026-47726 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

What actually determines whether CVE-2026-47726 is exploitable, and how bad it is?

Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.

How do I fix CVE-2026-47726?

Upgrade github.com/juev/nebula-mesh to 0.3.2 or later.
