GHSA-3mq9-xhgq-r7gj
MEDIUMGHSA-3mq9-xhgq-r7gj is a medium-severity (CVSS 5.9) CWE-522 vulnerability in github.com/lf-edge/eve. O3 Security confirms whether GHSA-3mq9-xhgq-r7gj is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
EVE: SSH as Root Unlockable Without Triggering Measured Boot
Blast Radius
github.com/lf-edge/eveReal-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
On boot, the Pillar container checks for /config/authorized_keys. If present with a valid public key, it enables SSH on port 22 with root login. The /config partition is not protected by measured boot, is mutable and unencrypted.
This enables an attacker with physical access to the device to take out the disk, modify the /config partition using a separate server, then insert it, without the inserted key being flagged as an integrity voilation my measured boot and remote attestation.
Patches
Patched in 9.4.3-lts
Workarounds
None (apart from preventing physical access to the device)
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/lf-edge/eve. 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/lf-edge/eve to 0.0.0-20220708121648-5fef4d92e758 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3mq9-xhgq-r7gj 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-3mq9-xhgq-r7gj 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-3mq9-xhgq-r7gj. 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-3mq9-xhgq-r7gj in your dependencies?
O3 detects GHSA-3mq9-xhgq-r7gj across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
