CVSSv3.1:

CVE-ID: CVE-2020-1747

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to insufficient validation of user-supplied input when processing untrusted YAML files passed via the "full_load" method or with the "FullLoader" loader. A remote attacker can pass specially crafted input to the application and execute arbitrary code by abusing the python/object/new constructor.

Mitigation

Install patches from vendor's website.
