Prior to 0.8.7, the @backstage/plugin-catalog-backend-module-gitlab package is affected by improper authorization in gitlab organizational user ingestion. Deployments that enable GitLab organization event ingestion and rely on scoped catalog users as an access boundary may admit an unintended catalog identity. Depending on sign-in and permission configuration, this may allow unauthorized access with the permissions of a standard authenticated user. This issue is fixed in version 0.8.7.","published":"2026-10-06T21:17:17.000Z","lastModified":"2026-10-22T18:52:52.000Z","status":"Analyzed","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":5.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N"},"cwe":["CWE-863"],"affected":["linuxfoundation/backstage\\/plugin-catalog-backend-module-gitlab","linuxfoundation/backstage"],"epss":{"score":0.00172,"percentile":0.0652,"date":"2026-10-27","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%).
