GHSA-w392-75q8-vr67 is a high-severity (CVSS 8.8) CWE-95 vulnerability in guardrails-ai. O3 Security confirms whether GHSA-w392-75q8-vr67 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Guardrails has an arbitrary code execution vulnerability
Real-World Exposure
guardrails-aiReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects PyPI packages — download data is not available via public APIs for these ecosystems.
Description
An arbitrary code execution vulnerability exists in versions 0.2.9 up to 0.5.10 of the Guardrails AI Guardrails framework because of the way it validates XML files. If a victim user loads a maliciously crafted XML file containing Python code, the code will be passed to an eval function, causing it to execute on the user's machine.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for guardrails-ai. 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 guardrails-ai to 0.5.10 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-w392-75q8-vr67 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 GHSA-w392-75q8-vr67 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-w392-75q8-vr67. 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-w392-75q8-vr67 in your dependencies?
O3 detects GHSA-w392-75q8-vr67 across PyPI dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
