CVE-2026-31072 - Apache APScheduler Python RCE via Insecure Deserialization

[Starburst-David]

CVE ID: CVE-2026-31072
Published: May 19, 2026, 4:16 p.m.
Description: 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
Severity: 0.0 | NA
