AI-suggested
Until a fix is available, users should avoid embedding sensitive credentials in proxy environment variables or restrict access to language server log files to prevent unauthorized disclosure. Consider configuring explicit http.proxy workspace settings to avoid logging environment variables.
Description
CVE-2026-59326 is a low-severity vulnerability in Spring Tools for Eclipse (version 5.2.0 and earlier) where the Spring Boot language server logs the raw value of proxy environment variables, including embedded Basic-auth credentials, at INFO level without redaction. This can lead to unintended disclosure of proxy credentials through log files, which may be accessible to other local users or attached to bug reports.
