CVE-2026-59327: CWE-312 Cleartext Storage of Sensitive Information in Spring Spring Tools for Eclipse
Spring Tools for Eclipse versions 5.2.0 and earlier store the Spring Boot DevTools remote secret in cleartext within Eclipse launch configuration files. These files are saved as XML in the workspace metadata or project directories, potentially exposing the secret if accessed via filesystem, backups, or version control. The secret protects the DevTools remote restart/reload endpoint, which can execute arbitrary class bytes on the target application. Exposure of this secret could allow an attacker with read access to the .launch file to perform remote code execution on the associated Spring Boot application.
AI Analysis
Technical Summary
CVE-2026-59327 describes a vulnerability in Spring Tools for Eclipse (<=5.2.0) where the Spring Boot DevTools remote secret (spring.devtools.remote.secret) is stored as a plaintext string attribute in the "Spring Boot DevTools Client" launch configuration. Eclipse persists these launch configurations as cleartext XML files either in workspace metadata or project directories if shared. Since this secret is the sole credential protecting the remote restart/reload endpoint that accepts and executes arbitrary class bytes, anyone with read access to the .launch file can extract the secret and potentially achieve remote code execution against the Spring Boot application.
Potential Impact
The vulnerability allows an attacker with read access to the Eclipse launch configuration files to obtain the DevTools remote secret. With this secret, the attacker can remotely execute arbitrary code on the Spring Boot application via the DevTools remote restart/reload endpoint. This compromises confidentiality and integrity of the application but does not directly affect availability. The CVSS score is 4.4 (medium), reflecting the requirement for local or limited access and user interaction.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should avoid sharing or committing .launch files containing the DevTools remote secret to version control or other shared locations. Restrict filesystem access to Eclipse workspace metadata and project directories to trusted users only. Consider disabling the remote DevTools feature if not needed.
