Until a fix is available, users should avoid using untrusted or compromised Initializr endpoints with the Spring Boot starter wizard in Spring Tools for Eclipse. Consider restricting network access or validating Initializr endpoints to reduce risk.
Description
CVE-2026-59328 is a cross-site scripting (XSS) vulnerability in Spring Tools for Eclipse up to version 5.2.0. It arises from rendering Spring Boot starter wizard dependency tooltips in an embedded browser with JavaScript enabled, where untrusted Initializr endpoints can inject arbitrary scripts. The impact is limited to UI spoofing within the IDE and outbound network beaconing, without full code execution.
