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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://github.com/web-infra-dev/rsdoctor/security/advisories/GHSA-jmg2-rcxh-w8q3","https://github.com/web-infra-dev/rsdoctor/security/advisories/GHSA-jmg2-rcxh-w8q3"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:56:02.509636177+00:00"},"epss":{"cve":"CVE-2026-61782","score":0.0043,"percentile":0.36977,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-jmg2-rcxh-w8q3","url":"https://osv.dev/vulnerability/GHSA-jmg2-rcxh-w8q3","summary":"@rsdoctor/rspack-plugin has Unauthenticated HTTP API that Exposes Project Source Code and Build Metadata","modified":"2026-09-24T20:00:05.116636767Z","packages":[{"ecosystem":"npm","name":"@rsdoctor/rspack-plugin","purl":"pkg:npm/%40rsdoctor/rspack-plugin","ranges":["<1.5.16"],"fixed":["1.5.16"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
