Real-World Exposure
github.com/omec-project/amfReal-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
A weakness has been identified in omec-project amf up to 2.1.3-dev. This affects an unknown function of the file ngap/handler.go of the component NGAP Message Handler. This manipulation causes null pointer dereference. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. Upgrading to version 2.2.0 mitigates this issue. It is recommended to upgrade the affected component. The same pull request fixes multiple security issues.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/omec-project/amf, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update github.com/omec-project/amf to 2.2.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-6h8r-h22r-jj64 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.
