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-3m3q-x3gj-f79x 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 377,636 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.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.

Summary
In certain reverse-proxy / forwarding setups, webhook verification can be bypassed if untrusted forwarded headers are accepted.
Impact
An external party may be able to send voice-call webhook requests that are accepted as valid, which can result in spoofed webhook events being processed.
Root Cause
Some deployments implicitly trusted forwarded headers (for example Forwarded / X-Forwarded-*) when determining request properties used during webhook verification. If those headers are not overwritten by a trusted proxy, a client can supply them directly and influence verification.
Resolution
Ignore forwarded headers by default unless explicitly trusted and allowlisted in configuration. Keep any loopback-only development bypass restricted to local development only. Upgrade to a patched version.
If you cannot upgrade immediately, strip Forwarded and X-Forwarded-* headers at the edge so clients cannot supply them directly.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @openclaw/voice-call, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update @openclaw/voice-call to 2026.2.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3m3q-x3gj-f79x 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-3m3q-x3gj-f79x can be triaged on real exposure rather than presence alone.
Tailored to GHSA-3m3q-x3gj-f79x. 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-3m3q-x3gj-f79x in your dependencies?
O3 Security finds GHSA-3m3q-x3gj-f79x across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
