GHSA-236h-rqv8-8q73 is a medium-severity (CVSS 6.5) CWE-863 vulnerability in parse-server. O3 Security confirms whether GHSA-236h-rqv8-8q73 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
GraphQL: Security breach on Viewer query
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
parse-servernpmDescription
Impact
An authenticated user using the viewer GraphQL query can bypass all read security on his User object and can also bypass all objects linked via relation or Pointer on his User object.
Patches

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for parse-server. 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 parse-server to 4.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-236h-rqv8-8q73 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-236h-rqv8-8q73 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-236h-rqv8-8q73. 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-236h-rqv8-8q73 in your dependencies?
O3 detects GHSA-236h-rqv8-8q73 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
