- Severity: CVSS 4.2 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-07-30 · Updated: 2026-07-30

## Affected

- Spring Spring Tools for Eclipse: through 5.2.0

## Description

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
