CVE-2026-22750 VMware CVE debrief

Who should care

Defenders and security teams responsible for Spring Cloud Gateway deployments should assess exposure and verify SSL configurations. This includes reviewing current SSL settings, understanding the implications of silent ignoring of custom SSL bundle configurations, and considering upgrades to supported open source releases. Security teams should prioritize verification of custom SSL bundle settings and ensure that appropriate measures are in place to manage

Why it matters

CVE-2026-22750's silent ignoring of custom SSL bundle configurations in Spring Cloud Gateway may expose certain deployments to security risks, requiring defenders to assess exposure, verify configurations, and consider upgrades.

• Potential security risks due to ignored custom SSL configurations
• Need for verification of SSL settings in existing deployments
• Possible upgrade requirements for affected versions

Technical summary

CVE-2026-22750: Spring Cloud Gateway's use of the configuration property spring.ssl.bundle silently ignores custom SSL bundle configurations, instead using default SSL settings. This may impact security in certain deployments, particularly those using Spring Cloud Gateway 4.2.0. Defenders should assess exposure and prioritize verification of SSL configurations in Spring Cloud Gateway deployments, considering upgrades to supported versions like 5.0.2 or 5.1.1 for enhanced security posture against potential risks associated with ignored custom SSL configurations.

Defensive priority

Defenders should assess exposure and prioritize verification of SSL configurations in Spring Cloud Gateway deployments.

Recommended defensive actions

• Review and verify SSL configurations in Spring Cloud Gateway deployments
• Assess exposure and prioritize verification of custom SSL bundle settings
• Consider upgrading to supported open source releases 5.0.2 or 5.1.1
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
