Summary
Apache Airflow and its SMTP and IMAP providers before specified versions are affected by the OpenSSL Certificate validation vulnerability. The default SSL context did not check the server's X.509 certificate, which could lead to the disclosure of mail server credentials or mail contents.
Risk Assessment
Organizations may be exposed to MITM attacks, potentially resulting in the loss of confidentiality of mail data. Disclosure of credentials may lead to further system compromises.
Recommendation
It is recommended 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.
Original NVD description (English source)
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
