Description
A vulnerability in Puppet 2.6.x before 2.6.15 and 2.7.x before 2.7.13, and Puppet Enterprise (PE) Users 1.0, 1.1, 1.2.x, 2.0.x, and 2.5.x before 2.5.1 allows remote authenticated users with agent SSL keys to (1) cause a denial of service (memory consumption) via a REST request to a stream that triggers a thread block, as demonstrated using CVE-2012-1986 and /dev/random; or (2) cause a denial of service (filesystem consumption) via crafted REST requests that use "a marshaled form of a Puppet::FileBucket::File object" to write to arbitrary file locations.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 💎RubyGems | puppet | ≥ 2.6.0&&< 2.6.15 | 2.6.15 |
| 💎RubyGems | puppet | ≥ 2.7.0&&< 2.7.13 | 2.7.13 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for puppet. 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 puppet to 2.6.15 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-v58w-6xc2-w799 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-v58w-6xc2-w799 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-v58w-6xc2-w799. 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-v58w-6xc2-w799 in your dependencies?
O3 detects GHSA-v58w-6xc2-w799 across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
