Prior to 2.2.4, the @backstage/plugin-techdocs-backend package is affected by improper authorization enforcement for techdocs static content. An authenticated user with access to one TechDocs documentation site could craft a URL able to read documentation belonging to a different entity. This only affects deployments using the external TechDocs builder with an external storage provider (S3, GCS, etc.) and the permission framework enabled. Instances that do not use the permission framework are unaffected, since TechDocs content is visible to all authenticated users by design. 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-rg9r-hr7g-5gc2","https://github.com/backstage/backstage/commit/bf6bbf7326ada7d96d7b2c4ebc4a71546106f311","https://github.com/backstage/backstage/releases/tag/v1.54.6"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-94008","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 6, 2026, 8:39:50 PM","dateUpdated":"Oct 7, 2026, 3:29:13 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
