GHSA-74cr-77xc-8g6r is a high-severity (CVSS 7.3) remote code execution vulnerability in @apollo/gateway. A fix is available for @apollo/gateway — see the affected versions and patch details below.
Prototype Pollution in @apollo/gateway
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.
@apollo/gatewaynpmDescription
Versions of @apollo/gateway prior to 0.6.2 are vulnerable to Prototype Pollution. The package uses deepMerge() to merge objects, which may allow attackers to alter the Object prototype through queries with GraphQL aliases. Carefully constructed payloads can override properties of all objects in the application. This may lead to Denial of Service or may be chained with other vulnerabilities leading to Remote Code Execution.
Recommendation
Upgrade to version 0.6.2 or later.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @apollo/gateway, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update @apollo/gateway to 0.6.2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-74cr-77xc-8g6r 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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-74cr-77xc-8g6r can be triaged on real exposure rather than presence alone.
Tailored to GHSA-74cr-77xc-8g6r. 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-74cr-77xc-8g6r in your dependencies?
O3 Security finds GHSA-74cr-77xc-8g6r across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
