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
CVE-2024-32964 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE sits: patch-first territory.
Where this sits among everything scored
Of 377,238 CVEs with a current EPSS score, this one falls in the 50–90% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure

@lobehub/chatnpmDescription
Lobe Chat is a chatbot framework that supports speech synthesis, multimodal, and extensible Function Call plugin system. Prior to 0.150.6, lobe-chat had an unauthorized Server-Side Request Forgery vulnerability in the /api/proxy endpoint. An attacker can construct malicious requests to cause Server-Side Request Forgery without logging in, attack intranet services, and leak sensitive information.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @lobehub/chat, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update @lobehub/chat to 0.150.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-32964 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 CVE-2024-32964 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2024-32964. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
