CVE-2026-59326

HTTP Proxy Credentials Logged in Plaintext by the Spring Boot Language Server

Published Jul 30, 2026 CVSS 3.1 · 3.3 Low EPSS < 1% KEV · Not listed
Description
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
