CVE-2026-59326
LowCVSS 3.3Exploitation Probability (EPSS)
Low risk1th percentile - higher than 1% of all known CVEs
Summary
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.
Risk Assessment
Proxy credentials can leak into log files, which are often attached to bug reports or accessible to other users/processes, potentially leading to unauthorized network access.
Recommendation
Update Spring Tools for Eclipse to a version later than 5.2.0 and Spring Tools for VSCode/Cursor/Theia to a version later than 2.2.0. Avoid storing credentials in proxy environment variables.
Original NVD description (English source)
The Spring Boot language server logs the raw value of the https_proxy/HTTPS_PROXY/http_proxy/HTTP_PROXY environment variable at INFO level whenever it creates an outbound HTTP client and no explicit http.proxy workspace setting is configured. Corporate proxy URLs frequently embed Basic-auth credentials in the form http://user:pass@proxy:8080, and the language server writes this value to its log file without any redaction. Since language server log files are often attached to bug reports or are readable by other local users/processes, this can result in disclosure of proxy credentials. Affected Spring Products and Versions: Spring Tools for Eclipse: 5.2.0 and earlier Spring Tools for VSCode / Cursor / Theia: 2.2.0 and earlier
