CVE-2026-59327 Details
Description
Spring Tools for Eclipse stores the Spring Boot DevTools remote secret (spring.devtools.remote.secret) as a plain string attribute on the "Spring Boot DevTools Client" launch configuration. Eclipse persists launch configuration attributes as cleartext XML, either to workspace metadata or, if the user marks the configuration as a shared file, directly into the project tree where it can be committed to version control. This secret is the sole credential protecting the DevTools remote restart/reload endpoint, which accepts and executes arbitrary class bytes on the target application. Anyone able to read the .launch file (via filesystem access, a workspace backup, or a shared VCS repository) can extract the secret and use it to achieve remote code execution against the associated Spring Boot application. Affected Spring Products and Versions: Spring Tools for Eclipse: 5.2.0 and earlier
A vulnerability exists in Spring Tools for Eclipse versions through 5.2.0, where the Spring Boot DevTools remote secret is stored as a plain string in the launch configuration. This secret is the only credential protecting the remote restart/reload endpoint, which can execute arbitrary class bytes on the target application. The cleartext secret can be extracted by anyone with access to the .launch file, either through filesystem access, a workspace backup, or a shared version control repository. Once obtained, the secret can be used to execute remote code on the associated Spring Boot application.
Users should upgrade to Spring Tools for Eclipse version 5.3.0. If a secret has been exposed, it is recommended to rotate the 'spring.devtools.remote.secret' on the affected application.
