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.
Other vulnerabilities in Spring Tools for Eclipse
See all- CVE-2026-59328Medium
Spring Tools for Eclipse renders Spring Boot starter wizard dependency tooltips in a native embedded browser with JavaScript enabled. Untrusted or compromised Initializr endpoints can lead to arbitrary script execution when hovering a dependency checkbox.
- CVE-2026-59327Medium
Spring Tools for Eclipse stores the Spring Boot DevTools remote secret as plain text in the launch configuration. The .launch file is saved as cleartext XML, potentially leaking the secret to the filesystem or version control.
- CVE-2026-47882High
When enabling Spring Boot DevTools support for a remote application target from the Spring Tools Boot Dashboard, Spring Tools generates a shared secret that authenticates DevTools remote-restart uploads. This secret was generated using a non-cryptographic pseudo-random number generator rather than a cryptographically secure source of randomness. Affects Spring Tools for Eclipse 5.2.0 and earlier.
- CVE-2026-47873High
The Boot Dashboard Docker integration in Spring Tools publishes container control ports on all of the host's network interfaces (0.0.0.0) rather than restricting them to loopback. Affects Spring Tools for Eclipse 5.2.0 and earlier.
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
