Versions prior to 5.0.0 provide an initial user with username `root` and password `root`. This is not ideal because attackers know that almost all vantage6 servers have a user with username `root` that probably has admin rights, and the initial password is very weak and it is possible that administrators forget to reset it. Version 5.0.0 fixes the issue. As a workaround, it is possible to delete the `root` user after it has been used to create other users.","published_at":"2026-06-17T22:14:51.461000Z","last_modified_at":null,"cvss_v3_score":null,"cvss_v3_vector":null,"cvss_v3_severity":null,"cvss_v4_score":6.9,"cvss_v4_vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N","cvss_v4_severity":"MEDIUM","ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-204","CWE-1393"],"nvd_references":["https://github.com/vantage6/vantage6/security/advisories/GHSA-fgmc-2hqj-86v4","https://github.com/vantage6/vantage6/issues/1932","https://github.com/vantage6/vantage6/blob/main/docs/release_notes.rst#500"],"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":"2026-06-28T23:30:54.391983Z"},"effective_severity":"MEDIUM","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":"N","value_label":"None"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"VC","name":"Confidentiality (Vulnerable System)","value":"L","value_label":"Low"},{"metric":"VI","name":"Integrity (Vulnerable System)","value":"L","value_label":"Low"},{"metric":"VA","name":"Availability (Vulnerable System)","value":"L","value_label":"Low"},{"metric":"SC","name":"Confidentiality (Subsequent System)","value":"N","value_label":"None"},{"metric":"SI","name":"Integrity (Subsequent System)","value":"N","value_label":"None"},{"metric":"SA","name":"Availability (Subsequent System)","value":"N","value_label":"None"}]},"affected":[{"vendor_slug":"vantage6","vendor_name":"vantage6","product_slug":"vantage6","product_name":"vantage6","version_start":"< 5.0.0","version_start_inclusive":true,"version_end":"< 5.0.0","version_end_inclusive":true,"cpe23_uri":"cve5:vantage6:vantage6:< 5.0.0:< 5.0.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/vantage6/vantage6/security/advisories/GHSA-fgmc-2hqj-86v4","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/vantage6/vantage6/issues/1932","source_type":"MISC","tags":[]},{"url":"https://github.com/vantage6/vantage6/blob/main/docs/release_notes.rst#500","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-06-17T22:14:51.461000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:37.240342Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:37.240342Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:37.240342Z","label":"CVSS score revised","source":"cvelistv5"}]}
