Description (CNA)
The JSONSerializer and CBORSerializer in APScheduler (all versions including 3.10.x and 4.0.0a5) are vulnerable to Remote Code Execution (RCE) via Insecure Deserialization. The unmarshal_object function allows for arbitrary class instantiation and state injection by dynamically importing modules and calling __setstate__ on any class available in the Python environment. An attacker can exploit this by submitting a specially crafted JSON or CBOR payload to an application using these serializers

No English description supplied.
A flaw was found in APScheduler, affecting its JSONSerializer and CBORSerializer components. This vulnerability, known as insecure deserialization, allows a remote attacker to execute arbitrary code on the system. By sending a specially crafted data payload, an attacker can manipulate the application to run malicious commands, potentially leading to a complete compromise of the affected system.
