Low risk6th percentile - higher than 6% of all known CVEs
Summary
Spring Tools for Eclipse renders Spring Boot starter wizard dependency tooltips in a native embedded browser with JavaScript enabled. Untrusted or compromised Initializr endpoints can lead to arbitrary script execution when hovering a dependency checkbox.
Risk Assessment
An attacker can perform in-IDE UI spoofing and outbound network beaconing, but not full code execution outside the IDE.
Recommendation
Update Spring Tools for Eclipse to a version later than 5.2.0. Use only trusted Initializr endpoints.
Other vulnerabilities in Spring Tools for Eclipse
See all- CVE-2026-59327Medium
Spring Tools for Eclipse stores the Spring Boot DevTools remote secret as plain text in the launch configuration. The .launch file is saved as cleartext XML, potentially leaking the secret to the filesystem or version control.
- CVE-2026-59326Low
The Spring Boot language server logs the raw value of proxy environment variables (https_proxy, etc.) at INFO level when no http.proxy setting is configured. Proxy URLs often contain Basic-auth credentials, which are written without redaction.
- CVE-2026-47882High
When enabling Spring Boot DevTools support for a remote application target from the Spring Tools Boot Dashboard, Spring Tools generates a shared secret that authenticates DevTools remote-restart uploads. This secret was generated using a non-cryptographic pseudo-random number generator rather than a cryptographically secure source of randomness. Affects Spring Tools for Eclipse 5.2.0 and earlier.
- CVE-2026-47873High
The Boot Dashboard Docker integration in Spring Tools publishes container control ports on all of the host's network interfaces (0.0.0.0) rather than restricting them to loopback. Affects Spring Tools for Eclipse 5.2.0 and earlier.
Original NVD description (English source)
Spring Tools for Eclipse renders Spring Boot starter wizard dependency tooltips in a native embedded browser (SWT Browser) with JavaScript enabled. Using untrusted and compromised Initializr endpoints for the Spring Boot starter wizard can result in arbitrary script execution inside the embedded browser when a developer hovers a dependency checkbox in the New Spring Starter Project wizard. Impact is limited to in-IDE UI spoofing and outbound network beaconing rather than full code execution. Affected Spring Products and Versions: Spring Tools for Eclipse: 5.2.0 and earlier
