{"cve":"CVE-2026-48089","nvd":{"published":"2026-06-19T20:16:16.583","modified":"2026-10-25T23:10:00.167","status":"Deferred","description":"DevGuard provides vulnerability management for the full software supply chain. Prior to 1.4.2, 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; and/or 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. Version `v1.4.2`contains a patch. As a workaround, 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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:H/SA:N","score":7.1},"cvss_v3":null,"cwes":["CWE-285","CWE-863"],"references":["https://github.com/l3montree-dev/devguard/commit/1be88ec1309a5dc0566e35a23bdc4ea3ecd11417","https://github.com/l3montree-dev/devguard/security/advisories/GHSA-6p54-fw2f-q7gf"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-48089","score":0.00364,"percentile":0.29993,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-6p54-fw2f-q7gf","url":"https://osv.dev/vulnerability/GHSA-6p54-fw2f-q7gf","summary":"DevGuard has improper authorization on public assets","modified":"2026-07-15T22:00:51.113908047Z","packages":[{"ecosystem":"Go","name":"github.com/l3montree-dev/devguard","purl":"pkg:golang/github.com/l3montree-dev/devguard","ranges":["<1.4.2"],"fixed":["1.4.2"]}]},{"id":"GO-2026-5183","url":"https://osv.dev/vulnerability/GO-2026-5183","summary":"DevGuard has improper authorization on public assets in github.com/l3montree-dev/devguard","modified":"2026-06-25T19:45:12.728000003Z","packages":[{"ecosystem":"Go","name":"github.com/l3montree-dev/devguard","purl":"pkg:golang/github.com/l3montree-dev/devguard","ranges":["<1.4.2"],"fixed":["1.4.2"]}]}],"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).
