{"cve":"CVE-2024-47762","nvd":{"published":"2024-10-03T18:15:05.287","modified":"2026-06-17T07:57:42.523","status":"Deferred","description":"Backstage is an open framework for building developer portals. Configuration supplied through APP_CONFIG_* environment variables, for example APP_CONFIG_backend_listen_port=7007, where unexpectedly ignoring the visibility defined in configuration schema. This occurred even if the configuration schema specified that they should have backend or secret visibility. This was an intended feature of the APP_CONFIG_* way of supplying configuration, but now clearly goes against the expected behavior of the configuration system. This behavior leads to a risk of potentially exposing sensitive configuration details intended to remain private or restricted to backend processes. The issue has been resolved in version 0.3.75 of the @backstage/plugin-app-backend package. As a temporary measure, avoid supplying secrets using the APP_CONFIG_ configuration pattern. Consider alternative methods for setting secrets, such as the environment substitution available for Backstage configuration.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","score":5.8},"cwes":["CWE-440"],"references":["https://github.com/backstage/backstage/commit/323e6129073c5cb4cc106a1239eaec31a129554f","https://github.com/backstage/backstage/security/advisories/GHSA-qc4v-xq2m-65wc"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:55:31.737901711+00:00"},"epss":{"cve":"CVE-2024-47762","score":0.00375,"percentile":0.3145,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-qc4v-xq2m-65wc","url":"https://osv.dev/vulnerability/GHSA-qc4v-xq2m-65wc","summary":"Unexpected visibility of environment variable configurations in @backstage/plugin-app-backend","modified":"2024-10-03T18:42:18.668681Z","packages":[{"ecosystem":"npm","name":"@backstage/plugin-app-backend","purl":"pkg:npm/%40backstage/plugin-app-backend","ranges":["<0.3.75"],"fixed":["0.3.75"]}]}],"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).
