Constellation allows Emergency shell access during initramfs boot phase
Real-World Exposure
github.com/edgelesssys/constellation/v2Real-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
Impact
An active attacker could let the boot fail on purpose in the initramfs, dropping the serial console into an emergency shell. This gives attackers with access to the serial console full control over the VM.
Patches
The issue has been patched in v2.6.0.
Workarounds

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/edgelesssys/constellation/v2, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/edgelesssys/constellation/v2 to 2.6.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6w5f-5wgr-qjg5 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-6w5f-5wgr-qjg5 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-6w5f-5wgr-qjg5. 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-6w5f-5wgr-qjg5 in your dependencies?
O3 Security finds GHSA-6w5f-5wgr-qjg5 across Go dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
