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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","score":5.4},"cwes":["CWE-863"],"references":["https://github.com/backstage/backstage/commit/c211b4b67d28efd2f4fac63e35e2ac515e305cb3","https://github.com/backstage/backstage/releases/tag/v1.54.6","https://github.com/backstage/backstage/security/advisories/GHSA-gp6m-x9vw-5c5x"],"products":["linuxfoundation:backstage","linuxfoundation:backstage\\/plugin-catalog-backend-module-gitlab"],"source":"nvd","synced_at":"2026-10-23T16:39:26.291718493+00:00"},"epss":{"cve":"CVE-2026-106463","score":0.00172,"percentile":0.06509,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-gp6m-x9vw-5c5x","url":"https://osv.dev/vulnerability/GHSA-gp6m-x9vw-5c5x","summary":"Backstage has improper authorization in GitLab organizational user ingestion","modified":"2026-10-07T18:15:10.729437546Z","packages":[{"ecosystem":"npm","name":"@backstage/plugin-catalog-backend-module-gitlab","purl":"pkg:npm/%40backstage/plugin-catalog-backend-module-gitlab","ranges":["<0.8.7"],"fixed":["0.8.7"]}]}],"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).
