CVE-2023-39441 Information

Description

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
