{"schema":"threatline.record/2","record":{"id":"CVE-2026-114489","aliases":[],"summary":"Missing Authorization in hMailServer","details":"Missing authorization in the REST and COM administration APIs of Progressive Robot hMailServer 6.0.0 through 6.3.6 allows a remote authenticated user whose credential is confined to named domains to change mail routing and domain configuration beyond those domains on a multi-tenant server. A domain administrator, an account or API key given another role that manages accounts in named domains, or a full-scope API key issued for named domains could create a domain alias for any name (so that other tenants' mail for that name is diverted to an address the attacker controls, or denied), rename a domain to any name the server does not host, set a rule's bind-to-address, send-using-route or script-function action to reach one of the server's own addresses, a configured route's stored credentials or a function of the server's event script, and set the domain's relay host - which delivery then connects to with no address rule - to an address on the server's own network; and over the COM API any account could set the three rule actions on its own rules, where the script-function action runs at delivery. The authorization gate did not refuse these routes to a confined credential and the handlers were not given the caller; over COM the domain-alias save performed no authorization check at all, the domain rename required only a domain administrator, and a rule save required at most that the caller could change the rule's owner.","categories":["Unclassified"],"product":"hMailServer","vendor":"Progressive Robot Ltd","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-114489","source_modified_at":"2026-10-21T15:34:06.371Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"hMailServer","vendor":"Progressive Robot Ltd","versions":[{"version":"6.0.0","status":"affected","lessThanOrEqual":"6.3.6","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00272,"percentile":0.1862,"score_date":"2026-10-23"},"published_at":"2026-10-21T15:34:06.371Z","modified_at":"2026-10-21T15:34:06.371Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-114489","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T15:34:06.371Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-114489","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://gitlab.com/hmailserver/hmailserver/-/work_items/86"},{"source":"CVE List","url":"https://gitlab.com/hmailserver/hmailserver/-/releases/v6.3.7"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-21T15:34:06.371Z","content_hash":"4a52dae945c300f8d28877f0fa4eb9c92b374edc1f0de2d68b740d905e2bf28a"}}
