GHSA-fcv6-fg5r-jm9q is a high-severity (CVSS 7.5) CWE-670 vulnerability in parse-server. O3 Security confirms whether GHSA-fcv6-fg5r-jm9q is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Trigger `beforeFind` not invoked in internal query pipeline when fetching pointer
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, a proxy for how much of the ecosystem is exposed.
parse-servernpmDescription
Impact
A Parse Pointer can be used to access internal Parse Server classes. It can also be used to circumvent the beforeFind query trigger which can be an additional vulnerability for deployments where the beforeFind trigger is used as a security layer to modify an incoming query.
Patches
The vulnerability was fixed by implementing a patch in the internal query pipeline to prevent a Parse Pointer to be used to access internal Parse Server classes or circumvent the beforeFind trigger.
Workarounds
There is no known workaround to prevent a Parse Pointer to be used to access internal Parse Server classes. A workaround if a beforeFind trigger is used as a security layer is to instead use the Parse Server provided security layers to manage access levels with Class-Level Permissions and Object-Level Access Control.

|---|---|---|---|
| 📦npm | parse-server | ≥ 1.0.0&&< 5.5.5 | 5.5.5 |

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 5.5.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-fcv6-fg5r-jm9q 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-fcv6-fg5r-jm9q 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-fcv6-fg5r-jm9q. 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-fcv6-fg5r-jm9q in your dependencies?
O3 detects GHSA-fcv6-fg5r-jm9q across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
