{"id":"CVE-2026-96627","summary":"Arcane: Delegated users:update permission allows admin account takeover via password reset (no privilege-hierarchy check)","details":"Arcane is an interface for managing Docker containers, images, networks, and volumes. Prior to 2.6.0, UpdateUser in backend/api/handlers/users.go sets PasswordHash for any target without comparing caller and target privilege. A holder of delegated users:update permission can submit a password change for the global administrator, replace the administrator password, and authenticate as that account, resulting in complete global administrator account takeover. This issue is fixed in version 2.6.0.","aliases":["GHSA-pw5q-rjx4-7f7p","GO-2026-6807"],"modified":"2026-10-21T03:00:21.423353168Z","published":"2026-10-16T21:13:16.717Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-266","CWE-269"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/96xxx/CVE-2026-96627.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/96xxx/CVE-2026-96627.json"},{"type":"FIX","url":"https://github.com/getarcaneapp/arcane/commit/21ea962f86d967dac8ae02a050f6e5f043d10fa1"},{"type":"FIX","url":"https://github.com/getarcaneapp/arcane/pull/3426"},{"type":"WEB","url":"https://github.com/getarcaneapp/arcane/releases/tag/backend/v2.6.0"},{"type":"ADVISORY","url":"https://github.com/getarcaneapp/arcane/security/advisories/GHSA-pw5q-rjx4-7f7p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-96627"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/getarcaneapp/arcane","events":[{"introduced":"0"},{"fixed":"b894618b0c310fce64823cec240516ef42880747"},{"fixed":"21ea962f86d967dac8ae02a050f6e5f043d10fa1"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"2.6.0"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"range":[{"fixed":"21ea962f86d967dac8ae02a050f6e5f043d10fa1"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["v2.5.0","types/v2.5.0","cli/v2.5.0","backend/v2.5.0","v2.4.0","types/v2.4.0","cli/v2.4.0","backend/v2.4.0","v2.3.2","types/v2.3.2","cli/v2.3.2","backend/v2.3.2","v2.3.1","types/v2.3.1","cli/v2.3.1","backend/v2.3.1","v2.3.0","types/v2.3.0","cli/v2.3.0","backend/v2.3.0","v2.2.0","types/v2.2.0","cli/v2.2.0","backend/v2.2.0","v2.1.0","types/v2.1.0","cli/v2.1.0","backend/v2.1.0","v2.0.3","types/v2.0.3","cli/v2.0.3","backend/v2.0.3","v2.0.2","types/v2.0.2","cli/v2.0.2","backend/v2.0.2","v2.0.1","types/v2.0.1","cli/v2.0.1","backend/v2.0.1","v2.0.0","types/v2.0.0","cli/v2.0.0","backend/v2.0.0","v1.20.0","types/v1.20.0","cli/v1.20.0","backend/v1.20.0","v1.19.5","types/v1.19.5","cli/v1.19.5","backend/v1.19.5","v1.19.4","types/v1.19.4","cli/v1.19.4","backend/v1.19.4","v1.19.3","types/v1.19.3","cli/v1.19.3","backend/v1.19.3","v1.19.2","types/v1.19.2","cli/v1.19.2","backend/v1.19.2","v1.19.1","types/v1.19.1","cli/v1.19.1","backend/v1.19.1","v1.19.0","types/v1.19.0","cli/v1.19.0","backend/v1.19.0","v1.18.1","types/v1.18.1","cli/v1.18.1","backend/v1.18.1","v1.18.0","types/v1.18.0","cli/v1.18.0","backend/v1.18.0","v1.17.4","types/v1.17.4","cli/v1.17.4","backend/v1.17.4","v1.17.3","types/v1.17.3","cli/v1.17.3","backend/v1.17.3","v1.17.2","types/v1.17.2","cli/v1.17.2","backend/v1.17.2","v1.17.1","types/v1.17.1","cli/v1.17.1","backend/v1.17.1","v1.17.0","types/v1.17.0","cli/v1.17.0","backend/v1.17.0","v1.16.3","types/v1.16.3","cli/v1.16.3","backend/v1.16.3","v1.16.2","types/v1.16.2","cli/v1.16.2","backend/v1.16.2","v1.16.1","types/v1.16.1","cli/v1.16.1","backend/v1.16.1","v1.16.0","types/v1.16.0","cli/v1.16.0","backend/v1.16.0","v1.15.3","types/v1.15.3","cli/v1.15.3","backend/v1.15.3","v1.15.2","types/v1.15.2","cli/v1.15.2","v1.15.1","types/v1.15.1","cli/v1.15.1","v1.15.0","types/v1.15.0","cli/v1.15.0","v1.14.1","v1.14.0","v1.13.2","v1.13.1","v1.13.0","v1.12.2","v1.12.1","v1.12.0","v1.11.3","v1.11.2","v1.11.1","v1.11.0","v1.10.1","v1.10.0","v1.9.0","v1.8.1","v1.8.0","v1.7.1","v1.7.0","v1.6.0","v1.5.2","v1.5.1","v1.5.0","v1.4.0","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.0","v1.0.2","v1.0.1","v1.0.0","v0.15.1","v0.15.0","v0.14.0","v0.13.1","v0.13.0","v0.12.0","v0.11.1","v0.11.0","v0.10.0","v0.9.2","v0.9.1","v0.9.0","v0.8.0","v0.7.1","v0.7.0","v0.6.0","v0.5.0","v0.4.1","v0.4.0","v0.3.0","v0.2.0","v0.1.1","v0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-96627.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
