Description

All versions of the package safe-eval are vulnerable to Sandbox Bypass due to improper input sanitization. The vulnerability is derived from prototype pollution exploitation. Exploiting this vulnerability might result in remote code execution (RCE).

Vulnerable functions:

defineGetter, stack(), toLocaleString(), propertyIsEnumerable.call(), valueOf().

Detection & mitigation playbook

Open-source dependency
  1. Detect

    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.

  2. Remediation status

    No patched version of safe-eval has shipped for GHSA-79xf-67r4-q2jj yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.

  3. 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.

  4. How O3 protects you

    O3 pinpoints whether GHSA-79xf-67r4-q2jj 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-79xf-67r4-q2jj. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
