Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-48089 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/l3montree-dev/devguard (Go): affected all versions; fixed in 1.4.2\n- github.com/l3montree-dev/devguard (Go): affected all versions; fixed in 1.4.2\n- github.com/l3montree-dev/devguard (Go): affected all versions; fixed in 1.4.2\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-48089/ (Markdown: https://insights.sbomify.com/CVE-2026-48089/index.md)","id":"CVE-2026-48089","markdown":"https://insights.sbomify.com/CVE-2026-48089/index.md","name":"CVE-2026-48089","record":{"aliases":["GHSA-6p54-fw2f-q7gf","GO-2026-5183"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"DevGuard vulnerability management","requires_auth":"low_privilege","summary":"Authenticated users can modify vulnerability data on public assets without proper authorization, requiring a patch or configuration change.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","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","version":"4.0"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-285","name":"Improper Authorization"}],"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.","ecosystems":["Go"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"DevGuard has improper authorization on public assets","id":"CVE-2026-48089","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"missing_authorization","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"Envoy HTTP: OAuth2 filter late async token completion after stream teardown (UAF / crash risk)","id":"CVE-2026-48090"},"packages":[{"ecosystem":"Go","fixed":["1.4.2"],"introduced":["0"],"last_affected":[],"package":"github.com/l3montree-dev/devguard","purl":null,"source":"GHSA-6p54-fw2f-q7gf"},{"ecosystem":"Go","fixed":["1.4.2"],"introduced":["0"],"last_affected":[],"package":"github.com/l3montree-dev/devguard","purl":"pkg:golang/github.com/l3montree-dev/devguard","source":"GHSA-6p54-fw2f-q7gf"},{"ecosystem":"Go","fixed":["1.4.2"],"introduced":["0"],"last_affected":[],"package":"github.com/l3montree-dev/devguard","purl":"pkg:golang/github.com/l3montree-dev/devguard","source":"GO-2026-5183"}],"prev":{"headline":"OpenReception vulnerable to unauthenticated staff crypto poisoning that breaks E2E recipient directory","id":"CVE-2026-48088"},"products":["devguard"],"published":"2026-06-19","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-22","vendors":["l3montree-dev"]},"summary":"Authenticated users can modify vulnerability data on public assets without proper authorization, requiring a patch or configuration change.","url":"https://insights.sbomify.com/CVE-2026-48089/"}
