Prior to version 2.3.6, in `EmailSender::add()`, the domain ownership validation for full email sender aliases uses the wrong array index when splitting the email address, passing the local part instead of the domain to `validateLocalDomainOwnership()`. This causes the ownership check to always pass for non-existent \"domains,\" allowing any authenticated customer to add sender aliases for email addresses on domains belonging to other customers. Postfix's `sender_login_maps` then authorizes the attacker to send emails as those addresses. Version 2.3.6 fixes the issue."}], "lastModified": "2026-06-17T10:46:21.300", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:froxlor:froxlor:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "9A9C896A-1305-4134-850E-4B44962A6C0A", "versionEndExcluding": "2.3.6"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
