CVE-2026-47873 Spring CVE debrief

Who should care

Users of Spring Tools for Eclipse, especially those using version 5.2.0 or earlier, should be aware of this vulnerability and take necessary precautions to mitigate the risk. Operators, platform administrators, vulnerability management teams, and security teams should review the affected scope and implement compensating controls to limit potential damage. They should also monitor network interfaces for suspicious activity and review incident response plans.

Technical summary

The Boot Dashboard Docker integration in Spring Tools publishes container control ports on all of the host's network interfaces (0.0.0.0) rather than restricting them to loopback. This allows potential attackers to access the container control ports from outside the host. The vulnerability affects Spring Tools for Eclipse, especially those using version 5.2.0 or earlier. Evidence is limited, and further verification is required to determine the full scope of the vulnerability. Defenders should verify the network configuration and monitor for suspicious activity.

Defensive priority

High-priority defensive actions are required due to the high CVSS score of 8 and the potential for significant impact.

Recommended defensive actions

• Verify the Spring Tools for Eclipse version and ensure it is not 5.2.0 or earlier.
• Restrict container control ports to loopback interfaces only.
• Monitor network interfaces for suspicious activity.
• Implement compensating controls to limit potential damage.
• Review and update incident response plans.
