node-cubenpmDescription
The node-cube package (prior to version 5.0.0) contains a vulnerability in its handling of prototype chain initialization, which could allow an attacker to inject properties into the prototype of built-in objects. This issue, categorized under CWE-1321, arises from improper validation of user-supplied input in the package's resource initialization process. Successful exploitation may lead to denial of service or arbitrary code execution in affected environments. The vulnerability affects versions up to and including 5.0.0-beta.19, and no official fix has been released to date.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for node-cube, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
No patched version of node-cube has shipped for CVE-2025-57348 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-2025-57348 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2025-57348. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
