{"id":"CVE-2026-114475","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-114475","generatedAt":"2026-10-27T23:59:30.503Z","title":"Missing authorization in the REST role-management routes of Progressive Robot hMailServer 6.3.4 through 6.3.6 allows a remote authenticated user whose credential is confined to named domains to modify a custom role that accounts in other domains hold,…","description":"Missing authorization in the REST role-management routes of Progressive Robot hMailServer 6.3.4 through 6.3.6 allows a remote authenticated user whose credential is confined to named domains to modify a custom role that accounts in other domains hold, and to create custom roles and delete any that no account holds. The routes that create, update and delete a custom role require the manage_roles permission, which only the serveradmin role holds; but a full-scope API key issued for named domains, and serveradmin assigned with a domain list, are serveradmin confined to those domains and hold manage_roles. The server's authorization gate did not refuse the three role routes to a confined credential and the route named no domain, so a credential issued to one tenant could raise or lower the permissions of a custom role assigned across other tenants - granting another domain's role every permission over its mailboxes and settings, or removing what it needs. A custom role may not hold administer_server, administer_domain or manage_roles, so the confined credential cannot make itself or another a server administrator by creating or rewriting a custom role.","published":"2026-10-21T16:17:35.000Z","lastModified":"2026-10-22T16:18:19.000Z","status":"Awaiting Analysis","sourceIdentifier":"cve@gitlab.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},"cwe":["CWE-862"],"affected":[],"epss":{"score":0.00237,"percentile":0.14582,"date":"2026-10-26","history":[{"date":"2026-10-22","score":0.00237,"percentile":0.13878}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.24%).
