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.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-61782 since 07/10/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.
