CVE-2026-47880 Spring CVE debrief

Who should care

Defenders responsible for Spring Integration deployments, especially those using JMS inbound components, should assess exposure and prioritize verification and remediation efforts.

Why it matters

A vulnerability in Spring Integration allows a producer to set String JMS properties that are copied into the Spring Integration MessageHeaders, potentially affecting the security of affected deployments.

• Defenders need to verify exposure in their Spring Integration deployments.
• Remediation requires updating to patched versions of Spring Integration.
• Monitoring for suspicious activity in affected environments is necessary.
• Exposure verification and remediation should be prioritized for deployments using JMS inbound components.

Technical summary

A producer who can publish to a JMS destination consumed by any Spring Integration JMS inbound component can set String JMS properties named replyChannel, errorChannel, or json__TypeId__ which are copied verbatim into the Spring Integration MessageHeaders. This issue affects Spring Integration versions 7.1.0, 7.0.0 - 7.0.5, 6.5.0 - 6.5.10, 6.4.0 - 6.4.12, and 5.5.21 and earlier. The vulnerability can be exploited by setting these properties, potentially affecting the security of affected deployments. Defenders should prioritize verifying exposure in their Spring Integration deployments, especially those using JMS inbound components.

Defensive priority

Defenders should prioritize verifying exposure in their Spring Integration deployments, especially those using JMS inbound components.

Recommended defensive actions

• Verify Spring Integration deployments for exposure, especially those using JMS inbound components.
• Check version numbers and apply patches according to vendor advisories.
• Monitor for suspicious activity in Spring Integration environments.
• Review compensating controls for exposed systems while remediation is scheduled and verified.
• Track exceptions, retest remediated assets, and close the item only after evidence is documented.
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, but the scope of affected deployments and specific remediation steps require verification from official sources. Affected deployments should be verified, especially those using JMS inbound components, and defenders should prioritize patching to mitigate potential risks. The issue requires careful review of Spring Integration configurations and JMS properties to ensure security.
