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.
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.
nocodbnpmDescription
NocoDB is software for building databases as spreadsheets. Prior to 2026.04.1, the password-reset page rendered the URL token directly into a JavaScript string literal in a server-rendered EJS template. EJS <%= %> HTML-entity-encodes a fixed set of characters but does not escape single quotes or backslashes, so a crafted token could break out of the JS string context and execute attacker-controlled script in the NocoDB origin. Triggering required only that a victim follow a malicious password-reset link. This vulnerability is fixed in 2026.04.1.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for nocodb. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update nocodb to 2026.04.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-47376 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 pinpoints whether CVE-2026-47376 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2026-47376. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
