CVE-2026-62242 codecentric CVE debrief

Who should care

Users of Spring Boot Admin Server versions before 4.1.2 should prioritize updating to the latest version to mitigate this vulnerability. This vulnerability affects operators who manage Spring Boot Admin Server deployments, as well as security teams responsible for vulnerability management. Platform administrators and security teams should review the official advisory and assess their exposure to this vulnerability.

Technical summary

The vulnerability exists in Spring Boot Admin Server before 4.1.2, allowing unauthenticated attackers to register instances with attacker-controlled healthUrl and managementUrl parameters. This can lead to server-side request forgery attacks, enabling attackers to force the server to make HTTP requests to arbitrary internal addresses and retrieve response bodies via the actuator proxy to exfiltrate cloud credentials. The vulnerability can be mitigated by updating to version 4.1.2 or later and implementing validation for healthUrl and managementUrl parameters.

Defensive priority

High priority should be given to updating Spring Boot Admin Server to version 4.1.2 or later. Implementing validation for healthUrl and managementUrl parameters and monitoring for suspicious activity related to instance registration are also crucial.

Recommended defensive actions

• Update Spring Boot Admin Server to version 4.1.2 or later
• Implement validation for healthUrl and managementUrl parameters
• Monitor for suspicious activity related to instance registration
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• 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
