### Impact On a DevGuard API instance with one or more **public assets**, any authenticated user — including users from a different organization with no membership or role in the affected org/project — can create, update, reapply, and delete **VEX rules** on those public assets. The same flaw affects the other vulnerability-triage write endpoints exposed under a public asset, including: - VEX rule create / update / reapply / delete - Dependency-vuln event creation (accept / reject / mitigate decisions), batch event creation, vuln sync, and mitigation - License risk creation - External reference writes - Artifact creation and license refresh The attacker needs a valid account on the instance, but no membership in the victim organization, project, or asset is required. **Security impact** is primarily to **integrity** of the vulnerability picture of public assets: an attacker can mark CVEs as false-positive, silence vulnerabilities, attach misleading justifications, or delete legitimate triage rules — undermining the trustworthiness of every consumer of the affected asset's VEX/SBOM output. Because public assets are by definition consumed by third parties (downstream users, supply-chain consumers, the published vex.json/sbom.json), the blast radius extends to anyone relying on that data. Private assets are **not affected** by this advisory: the public-read exemption that enables the bypass does not apply to them, and access remains correctly gated by organization/project membership. The private setting is only relevant in DevGuard itself — there is no impact given when you have an open-source project on e.g. GitLab/GitHub and a private DevGuard asset connected. ### Patches Version `v1.4.2`contains a patch. Users should upgrade to the patched release as soon as it is available. ### Workarounds If developers cannot upgrade their applications immediately: - ** They should make affected assets non-public.** In the asset settings, switch visibility from public to private. This removes the public-read exemption in the access-control middleware and restores correct authorization on all write endpoints for that asset. Downstream consumers that previously relied on the public `vex.json` / `sbom.json` endpoints will need to be granted explicit access or must receive an exported file version until the patched release is deployed. ### Resources Fixed commit: https://github.com/l3montree-dev/devguard/commit/1be88ec1309a5dc0566e35a23bdc4ea3ecd11417 ### Credit DeevGuard thanks @philipflohr ([awesome-it.de](https://awesome-it.de/)) for finding and responsibly reporting this vulnerability!

AI coding agents often install or upgrade packages automatically in go. A high vulnerability in a dependency can be pulled into a project through a normal install or update without a human reviewing the change, expanding the blast radius from a single package to every agent workspace that depends on it.
