Prior to 1.14.6 and 1.15.4, the @backstage/plugin-techdocs-node package did not sufficiently validate TechDocs Markdown extension configuration. An authenticated user who can register or modify documentation sources may cause a TechDocs build to access resources outside the intended documentation boundary, potentially exposing backend-host data or internal network resources. This issue is fixed in versions 1.14.6 and 1.15.4 when pymdown-extensions 10.21.3 or later is also used, normally through mkdocs-techdocs-core 1.7.0 or later.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7,"severity":null}],"references":["https://github.com/backstage/backstage/security/advisories/GHSA-f7v3-xhm6-w245","https://github.com/backstage/backstage/commit/017ace52d9b327ededc6704cf17799c875ae0f29","https://github.com/backstage/backstage/commit/2d9de4ca117a529de4b6ed7dfb7aa507ca7b3f91","https://github.com/backstage/backstage/releases/tag/v1.50.5","https://github.com/backstage/backstage/releases/tag/v1.54.6"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-94482","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 7, 2026, 4:22:53 PM","dateUpdated":"Oct 7, 2026, 5:47:16 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
