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.","state":0,"publishedAt":"2026-10-16T21:13:16.717+00:00","modifiedAt":"2026-10-19T14:34:05.584+00:00","affected":[{"ecosystem":"Vendor product","name":"arcane","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"getarcaneapp\",\n                    \"product\": \"arcane\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.6.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://github.com/getarcaneapp/arcane/security/advisories/GHSA-pw5q-rjx4-7f7p","https://github.com/getarcaneapp/arcane/pull/3426","https://github.com/getarcaneapp/arcane/commit/21ea962f86d967dac8ae02a050f6e5f043d10fa1","https://github.com/getarcaneapp/arcane/releases/tag/backend/v2.6.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-96627","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-96627","identifiers":["CVE-2026-96627"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
