GHSA-55q8-2gwx-29pc
MEDIUMGHSA-55q8-2gwx-29pc is a medium-severity (CVSS 6.5) NULL Pointer Dereference vulnerability in github.com/ellanetworks/core. O3 Security confirms whether GHSA-55q8-2gwx-29pc is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Description
Summary
Ella Core panics when processing Authentication Response and Authentication Failure NAS message missing IEs.
Impact
An attacker able to send crafted NAS messages to Ella Core can crash the process, causing service disruption for all connected subscribers. No authentication is required.
Fix
Added IE presence verification to NAS message handling.
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/ellanetworks/core. 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/ellanetworks/core to 1.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-55q8-2gwx-29pc 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-55q8-2gwx-29pc 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-55q8-2gwx-29pc. 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-55q8-2gwx-29pc in your dependencies?
O3 detects GHSA-55q8-2gwx-29pc across Go dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
