CVE-2026-61782
@rsdoctor/rspack-plugin has Unauthenticated HTTP API that Exposes Project Source Code and Build Metadata
Description
Rsdoctor is a build analyzer tailored for projects built with Rspack. Prior to version 1.5.16, the default Rsdoctor report HTTP server started by `@rsdoctor/rspack-plugin` binds to all network interfaces (`0.0.0.0`) and serves a `POST /api/data/key` endpoint with no authentication and wildcard CORS (`Access-Control-Allow-Origin: *`). Any network-adjacent or remote attacker can send a single unauthenticated request to retrieve the full source code of all compiled JavaScript modules (`moduleCodeMap`), serialized build configuration (`configs`), error details, and other sensitive build metadata. This server is enabled by default in non-CI environments, requiring no special configuration from the victim developer. Version 1.5.16 patches the issue.
