CVE-2026-44127 affects SEPPmail Secure Email Gateway before version 15.0.4. The vulnerability is an unauthenticated path traversal in the identifier parameter of the /api.app/attachment/preview endpoint in the GINA v2 interface. By supplying crafted path traversal sequences, a remote attacker can cause the application to access arbitrary local files outside the intended attachment directory. The available reporting indicates this behavior enables local file inclusion/arbitrary file read against files reachable by the api.app process, including sensitive appliance data such as emails, LDAP databases, credentials, password hashes, and keys. The same vulnerable code path also attempts to delete the parent folder of the referenced object, which can be abused to trigger deletion of files in the targeted directory with the privileges of the api.app process.
