CVE-2026-40976 (GCVE-0-2026-40976)
Vulnerability from cvelistv5 – Published: 2026-04-27 23:34 – Updated: 2026-07-15 01:00

VEX
Summary
In certain circumstances, Spring Boot's default web security is ineffective allowing unauthorized access to all endpoints. For an application to be vulnerable, it must: be a servlet-based web application; have no Spring Security configuration of its own and rely on the default web security filter chain; depend on spring-boot-actuator-autoconfigure; not depend on spring-boot-health. If any of the above does not apply, the application is not vulnerable.
Affected: Spring Boot 4.0.0–4.0.5; upgrade to 4.0.6 or later per vendor advisory.
Severity
9.1 (Critical)
SSVC
Exploitation: none
Automatable: yes
