Prior to 1.54.6, scaffolder source-control actions may not consistently enforce intended credential boundaries. An authenticated user could cause an affected action to fall back to broader integration credentials and perform operations with more access than intended. This issue is fixed in 1.54.6 when operators also enable scaffolder.requireScmUserCredentials after upgrading.","published":"2026-10-06T21:17:17.000Z","lastModified":"2026-10-22T18:53:09.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},"cwe":["CWE-441","CWE-863"],"affected":["linuxfoundation/backstage\\/plugin-scaffolder-backend","linuxfoundation/backstage\\/plugin-scaffolder-backend-module-azure","linuxfoundation/backstage\\/plugin-scaffolder-backend-module-bitbucket-cloud","linuxfoundation/backstage\\/plugin-scaffolder-backend-module-bitbucket-server","linuxfoundation/backstage\\/plugin-scaffolder-backend-module-github","linuxfoundation/backstage\\/plugin-scaffolder-backend-module-gitlab","linuxfoundation/backstage"],"epss":{"score":0.00172,"percentile":0.06514,"date":"2026-10-26","history":[{"date":"2026-10-07","score":0.00171,"percentile":0.05943}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.17%).
