The same flaw affects the other vulnerability-triage write endpoints exposed under a public asset, including:\n\n- VEX rule create / update / reapply / delete\n- Dependency-vuln event creation (accept / reject / mitigate decisions), batch event creation, vuln sync, and mitigation\n- License risk creation\n- External reference writes\n- Artifact creation and license refresh\n\nThe attacker needs a valid account on the instance, but no membership in the victim organization, project, or asset is required.\n\n**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.\n\nPrivate 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.\n\n### Patches\n\nVersion `v1.4.2`contains a patch. Users should upgrade to the patched release as soon as it is available.\n\n### Workarounds\n\nIf developers cannot upgrade their applications immediately:\n\n- ** They should make affected assets non-public.** In the asset settings, switch visibility from public to private.
