Technical description

An issue was discovered in Bloop Airmail 3 3.5.9 for macOS. It registers and uses the airmail:// URL scheme. The "send" command in the URL scheme allows an external application to send arbitrary emails from an active account without authentication. The handler has no restriction on who can use its functionality. The handler can be invoked using any method that invokes the URL handler such as a hyperlink in an email. The user is not prompted when the handler processes the "send" command, thus leading to automatic transmission of an attacker crafted email from the target account.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
