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 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 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 achieve remote code execution. The vulnerability has a medium severity with a CVSS score of 4.4.
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 plain string attribute in the "Spring Boot DevTools Client" launch configuration. Eclipse persists these launch configurations as cleartext XML files in workspace metadata or project directories, which may be shared or committed to version control. Since this secret is the sole credential protecting the DevTools remote restart/reload endpoint, anyone who can read the .launch file can extract the secret and use it to remotely execute arbitrary class bytes on the associated Spring Boot application. This cleartext storage of sensitive information corresponds to CWE-312.
Potential Impact
The vulnerability allows an attacker with read access to the 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 the confidentiality and integrity of the application but does not directly affect availability. The CVSS score is 4.4 (medium severity), reflecting the requirement for local or limited access and user interaction.
Mitigation Recommendations
No official patch or fix is currently documented for this vulnerability. Users should avoid sharing or committing .launch files containing the spring.devtools.remote.secret to version control or other shared locations. Restrict filesystem access to workspace metadata and project directories to trusted users only. Monitor vendor advisories for updates or official fixes addressing this issue.
