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-g95c-2jgm-hqc6 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 377,333 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
Impact
The Fides webserver is vulnerable to a type of Denial of Service (DoS) attack. Attackers can exploit a weakness in the connector template upload feature to upload a malicious zip bomb file, resulting in resource exhaustion and service unavailability for all users of the Fides webserver.
This vulnerability affects Fides versions 2.11.0 through 2.15.1. Exploitation is limited to users with elevated privileges with the CONNECTOR_TEMPLATE_REGISTER scope, which includes root users and users with the owner role.
Patches
The vulnerability has been patched in Fides version 2.16.0. Users are advised to upgrade to this version or later to secure their systems against this threat.
Workarounds
There is no known workaround to remediate this vulnerability without upgrading. If an attack occurs, the impact can be mitigated by manually or automatically restarting the affected container.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ethyca-fides, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update ethyca-fides to 2.16.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g95c-2jgm-hqc6 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-g95c-2jgm-hqc6 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-g95c-2jgm-hqc6. 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-g95c-2jgm-hqc6 in your dependencies?
O3 Security finds GHSA-g95c-2jgm-hqc6 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
