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.","published_at":"2026-06-19T19:38:04.175000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":7.1,"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","cvss_v4_severity":"HIGH","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-285","CWE-863"],"nvd_references":["https://github.com/l3montree-dev/devguard/security/advisories/GHSA-6p54-fw2f-q7gf","https://github.com/l3montree-dev/devguard/commit/1be88ec1309a5dc0566e35a23bdc4ea3ecd11417"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:42.802049Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":null,"metrics":[]},"cvss_v4_decoded":{"version":"4.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"AT","name":"Attack Requirements","value":"P","value_label":"Present"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"N","value_label":"None"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"H","value_label":"High"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"H","value_label":"High"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"H","value_label":"High"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"l3montree-dev","vendor_name":"l3montree-dev","product_slug":"devguard","product_name":"devguard","version_start":"< 1.4.2","version_start_inclusive":true,"version_end":"< 1.4.2","version_end_inclusive":true,"cpe23_uri":"cve5:l3montree-dev:devguard:< 1.4.2:< 1.4.2"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/l3montree-dev/devguard/security/advisories/GHSA-6p54-fw2f-q7gf","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/l3montree-dev/devguard/commit/1be88ec1309a5dc0566e35a23bdc4ea3ecd11417","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-06-19T19:38:04.175000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:03.830140Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:03.830140Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:03.830140Z","label":"CVSS score revised","source":"cvelistv5"}]}
