GHSA-ww6v-677g-p656
CRITICALGHSA-ww6v-677g-p656 is a critical-severity (CVSS 10) CWE-610 vulnerability in safe-eval. O3 Security confirms whether GHSA-ww6v-677g-p656 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
safe-evalnpmDescription
Affected versions of safe-eval are vulnerable to a sandbox escape. By accessing object constructors, un-sanitized user input can access the entire standard library and effectively break out of the sandbox.
Proof of Concept:
This code accesses the process object and calls .exit()
var safeEval = require('safe-eval');
safeEval("this.constructor.constructor('return process')().exit()");
Recommendation
Update to version 0.4.0 or later

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for safe-eval. 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.
Remediation status
No patched version of safe-eval has shipped for GHSA-ww6v-677g-p656 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 pinpoints whether GHSA-ww6v-677g-p656 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 GHSA-ww6v-677g-p656. 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-ww6v-677g-p656 in your dependencies?
O3 detects GHSA-ww6v-677g-p656 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
