Spring Boot applications with Actuator can be vulnerable to an "Authentication Bypass" vulnerability when an application endpoint that requires authentication is declared under a specific path, already configured for a Health Group additional path.

This CVE is similar but not equivalent to CVE-2026-22733, as the conditions for exploit and vulnerable versions are different.
