What is CVE-2026-61782?

The Rsdoctor build analyzer, specifically tailored for Rspack projects, was found to have a significant vulnerability prior to version 1.5.16. A default HTTP server can bind to all network interfaces, exposing the sensitive /api/data/key endpoint without authentication. This flaw allows network-adjacent or remote attackers to send unauthorized requests, potentially retrieving sensitive information such as the full source code of compiled JavaScript modules, build configurations, error details, and other proprietary build metadata. This vulnerability, enabled by default in non-CI environments, poses a substantial risk to developers who do not alter the default configuration. The issue is resolved in version 1.5.16.
