{"cve":"CVE-2024-53983","nvd":{"published":"2024-11-29T19:15:10.137","modified":"2026-06-17T08:09:36.860","status":"Deferred","description":"The Backstage Scaffolder plugin Houses types and utilities for building scaffolder-related modules. A vulnerability is identified in Backstage Scaffolder template functionality where Server-Side Template Injection (SSTI) can be exploited to perform Git config injection. The vulnerability allows an attacker to capture privileged git tokens used by the Backstage Scaffolder plugin. With these tokens, unauthorized access to sensitive resources in git can be achieved. The impact is considered medium severity as the Backstage Threat Model recommends restricting access to adding and editing templates in the Backstage Catalog plugin. The issue has been resolved in versions `v0.4.12`, `v0.5.1` and `v0.6.1` of the `@backstage/plugin-scaffolder-node` package. Users are encouraged to upgrade to this version to mitigate the vulnerability. Users are advised to upgrade. Users unable to upgrade may ensure that templates do not change git config.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:N/A:N","score":5.4},"cwes":["CWE-918"],"references":["https://github.com/backstage/backstage/security/advisories/GHSA-qmc2-jpr5-7rg9","https://github.com/backstage/backstage/tree/master/plugins/scaffolder-node"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:57:34.731061660+00:00"},"epss":{"cve":"CVE-2024-53983","score":0.00373,"percentile":0.31246,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-qmc2-jpr5-7rg9","url":"https://osv.dev/vulnerability/GHSA-qmc2-jpr5-7rg9","summary":"Backstage Scaffolder plugin vulnerable to Server-Side Request Forgery","modified":"2024-12-02T21:59:39.558003Z","packages":[{"ecosystem":"npm","name":"@backstage/plugin-scaffolder-node","purl":"pkg:npm/%40backstage/plugin-scaffolder-node","ranges":["<0.4.12"],"fixed":["0.4.12"]},{"ecosystem":"npm","name":"@backstage/plugin-scaffolder-node","purl":"pkg:npm/%40backstage/plugin-scaffolder-node","ranges":[">=0.5.0 <0.5.1"],"fixed":["0.5.1"]},{"ecosystem":"npm","name":"@backstage/plugin-scaffolder-node","purl":"pkg:npm/%40backstage/plugin-scaffolder-node","ranges":[">=0.6.0 <0.6.1"],"fixed":["0.6.1"]}]}],"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).
