HIGHGHSA-hggv-mcp4-vxc5 is a high-severity (CVSS 7.5) Missing Authentication vulnerability in freetakserver. 1 public exploit reference exists, so weaponization risk is real. A fix is available for freetakserver — see the affected versions and patch details below.
Improper Authentication in FreeTAKServer
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-hggv-mcp4-vxc5 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,166 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.

Description
FreeTAKServer is an open source, lightweight Server for connect TAK clients. An access control issue in the component /ManageRoute/postRoute of FreeTAKServer version 1.9.8 allows unauthenticated attackers to cause a Denial of Service (DoS) via an unusually large amount of created routes, or create unsafe or false routes for legitimate users. There is currently no known workaround. This issue was fixed in version 1.9.8.5.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for freetakserver, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update freetakserver to 1.9.8.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hggv-mcp4-vxc5 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-hggv-mcp4-vxc5 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-hggv-mcp4-vxc5. 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-hggv-mcp4-vxc5 in your dependencies?
O3 Security finds GHSA-hggv-mcp4-vxc5 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
