Apache Airflow SMTP Provider, Apache Airflow IMAP Provider, Apache Airflow: SMTP/IMAP client components allowed MITM due to missing Certificate Validation
CVE-2023-39441

5.9MEDIUM

What is CVE-2023-39441?

Apache Airflow SMTP Provider before 1.3.0, Apache Airflow IMAP Provider before 3.3.0, and Apache Airflow before 2.7.0 are affected by the Validation of OpenSSL Certificate vulnerability.

The default SSL context with SSL library did not check a server's X.509 certificate.  Instead, the code accepted any certificate, which could result in the disclosure of mail server credentials or mail contents when the client connects to an attacker in a MITM position.

Users are strongly advised to upgrade to Apache Airflow version 2.7.0 or newer, Apache Airflow IMAP Provider version 3.3.0 or newer, and Apache Airflow SMTP Provider version 1.3.0 or newer to mitigate the risk associated with this vulnerability

Affected Version(s)

Apache Airflow 0 < 2.7.0

Apache Airflow IMAP Provider 0 < 3.3.0

Apache Airflow SMTP Provider 0 < 1.30
