Prior to 2.2.4, the @backstage/plugin-techdocs-backend package is affected by improper input validation in techdocs static content requests. When using the Azure Blob Storage provider, an authenticated Backstage user may be able to read restricted TechDocs content when entity-level permissions are enabled. Deployments that intentionally disable the default backend authentication policy may have broader exposure. This issue is fixed in version 2.2.4.","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:U/C:H/I:N/A:N","score":6.5,"severity":null}],"references":["https://github.com/backstage/backstage/security/advisories/GHSA-7mfx-xg57-53c9","https://github.com/backstage/backstage/commit/40ecc4c2e88b0218125b0a3405d1f6315b321974","https://github.com/backstage/backstage/releases/tag/v1.54.6"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-94009","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 6, 2026, 8:41:26 PM","dateUpdated":"Oct 7, 2026, 5:06:57 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
