When using the AWS S3 or GCS storage provider for TechDocs it is possible to access content in the entire storage bucket. This can leak contents of the bucket that are not intended to be accessible, as well as bypass permission checks in Backstage. This has been fixed in the 1.10.13 release of the `@backstage/plugin-techdocs-backend` package. All users are advised to upgrade. There are no known workarounds for this vulnerability.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-22","CWE-23"],"references":["https://github.com/backstage/backstage/security/advisories/GHSA-39v3-f278-vj3g"],"products":["linuxfoundation:backstage"],"source":"nvd","synced_at":"2026-10-19T21:54:38.012257375+00:00"},"epss":{"cve":"CVE-2024-45816","score":0.00728,"percentile":0.54193,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-39v3-f278-vj3g","url":"https://osv.dev/vulnerability/GHSA-39v3-f278-vj3g","summary":"@backstage/plugin-techdocs-backend storage bucket Directory Traversal vulnerability","modified":"2025-01-03T16:12:39Z","packages":[{"ecosystem":"npm","name":"@backstage/plugin-techdocs-backend","purl":"pkg:npm/%40backstage/plugin-techdocs-backend","ranges":["<1.10.13"],"fixed":["1.10.13"]}]}],"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).
