CVE-2026-22750
HIGHCVE-2026-22750 is a high-severity (CVSS 7.5) CWE-15 vulnerability in org.springframework.cloud:spring-cloud-gateway. O3 Security confirms whether CVE-2026-22750 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
SSL bundle configuration silently bypassed in Spring Cloud Gateway
Blast Radius
org.springframework.cloud:spring-cloud-gatewayReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
When configuring SSL bundles in Spring Cloud Gateway by using the configuration property spring.ssl.bundle, the configuration was silently ignored and the default SSL configuration was used instead. Note: The 4.2.x branch is no longer under open source support. If you are using Spring Cloud Gateway 4.2.0 and are not an enterprise customer, you can upgrade to any Spring Cloud Gateway 4.2.x release newer than 4.2.0 available on Maven Centeral https://repo1.maven.org/maven2/org/springframework/cloud/spring-cloud-gateway/ . Ideally if you are not an enterprise customer, you should be upgrading to 5.0.2 or 5.1.1 which are the current supported open source releases.

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 4.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-22750 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 CVE-2026-22750 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 CVE-2026-22750. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
