Description
Applications using Spring Cloud Gateway are vulnerable to specifically crafted requests that could make an extra request on downstream services. Users of affected versions should apply the following mitigation: 3.0.x users should upgrade to 3.0.5+, 2.2.x users should upgrade to 2.2.10.RELEASE or newer.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.springframework.cloud:spring-cloud-gateway | ≥ 3.0.0&&< 3.0.5 | 3.0.5 |
| ☕Maven | org.springframework.cloud:spring-cloud-gateway | ≥ 2.2.0&&< 2.2.10.RELEASE0.5 | 2.2.10.RELEASE0.5 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.springframework.cloud:spring-cloud-gateway. 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 org.springframework.cloud:spring-cloud-gateway to 3.0.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-2r2v-q399-qq93 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-2r2v-q399-qq93 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-2r2v-q399-qq93. 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-2r2v-q399-qq93 in your dependencies?
O3 detects GHSA-2r2v-q399-qq93 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
