CVE-2023-50943 Open this link in a new tabHow to fix?
Upgrade apache-airflow to version 2.8.1 or higher.
Overview
apache-airflow is a platform to programmatically author, schedule, and monitor workflows.
Affected versions of this package are vulnerable to Deserialization of Untrusted Data due to improper validation of input during the deserialization process of XCom data. An attacker can execute arbitrary code by submitting crafted input that bypasses the protection of the enable_xcom_pickling=False configuration setting, leading to poisoned data after deserialization.
Details
Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.
Deserialization of untrusted data (CWE-502) is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, thus allowing the attacker to control the state or the flow of the execution.
