{"id":"CVE-2024-53983","aliases":["GHSA-qmc2-jpr5-7rg9"],"url":"https://o3.security/vulnerability/CVE-2024-53983","summary":"Server-side request forgery in Backstage Scaffolder plugin","details":"### Impact\n\nA 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.\n\n### Patches\n\nThe 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.\n\n### Workarounds\n\nUsers can ensure that templates do not change git config.\n\n### References\n\nIf you have any questions or comments about this advisory:\n\nOpen an issue in the [Backstage repository](https://github.com/backstage/backstage)\nVisit our Discord, linked to in [Backstage README](https://github.com/backstage/backstage)","published":"2024-11-29T18:53:13.289Z","modified":"2026-08-12T03:51:40.004303390Z","cvss":{"score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@backstage/plugin-scaffolder-node","fixedVersion":"0.4.12"},{"ecosystem":"npm","name":"@backstage/plugin-scaffolder-node","fixedVersion":"0.5.1"},{"ecosystem":"npm","name":"@backstage/plugin-scaffolder-node","fixedVersion":"0.6.1"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/backstage/backstage/tree/master/plugins/scaffolder-node"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53983.json"},{"type":"ADVISORY","url":"https://github.com/backstage/backstage/security/advisories/GHSA-qmc2-jpr5-7rg9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53983"},{"type":"PACKAGE","url":"https://github.com/backstage/backstage"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:40.004303390Z"}}
