CVE-2026-59327

Remote code execution via cleartext DevTools secret

Published Jul 30, 2026 · Updated Jul 30, 2026

Cleartext credential storage in Spring Tools for Eclipse 5.2.0 and earlier allows local users to obtain a DevTools remote secret. The Spring Boot DevTools Client launch configuration writes spring.devtools.remote.secret as a plain string, and Eclipse persists that attribute in cleartext XML. Reading a workspace or shared .launch file exposes the sole endpoint credential, enabling remote class-byte execution against the associated application.
