CVE-2026-48089Network attack vector

Cross-organization data tampering via public-read exemption

Published Jun 19, 2026 · Updated Jun 19, 2026

Incorrect authorization in l3montree GmbH DevGuard before 1.4.2 allows remote authenticated users to alter public-asset triage data. The asset access-control middleware treated public-read context as sufficient while write routes lacked public-request rejection or asset-scoped RBAC checks. A valid instance account and a public victim asset are required; successful requests can falsify VEX/SBOM-derived decisions or delete legitimate triage state.
