CVE-2023-23943 Nextcloud mail is an email app for the nextcloud home server platform. In affected versions the SMTP, IMAP and Sieve host fields allowed to scan for internal services and servers reachable from within the local network of the Nextcloud Server.

The only known workaround for this issue is to completely disable the nextcloud mail app. References: http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2023-23943 https://www.cve.org/CVERecord?id=CVE-2023-23943 https://github.com/nextcloud/mail/pull/7796 https://github.com/nextcloud/security-advisories/security/advisories/GHSA-8gcx-r739-9pf6 https://hackerone.com/reports/1741525 https://hackerone.com/reports/1736390 https://hackerone.com/reports/1746582
