CVE-2022-25967
HIGHCVE-2022-25967 is a high-severity (CVSS 8.1) Code Injection vulnerability in eta. O3 Security confirms whether CVE-2022-25967 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Eta vulnerable to Code Injection via templates rendered with user-defined data
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
etanpmDescription
Versions of the package eta before 2.0.0 are vulnerable to Remote Code Execution (RCE) by overwriting template engine configuration variables with view options received from The Express render API.
Note: This is exploitable only for users who are rendering templates with user-defined data.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for eta. 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 eta to 2.0.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-25967 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-2022-25967 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-2022-25967. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2022-25967 in your dependencies?
O3 detects CVE-2022-25967 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
