CWE-20Published: August 20, 2020· Updated: Jun 17, 2026

8.8

CVSS v3.1

Official Description

Use of unsafe yaml load. Allows instantiation of arbitrary objects. The flaw itself is caused by an unsafe parsing of YAML values which happens whenever an action message is processed to be sent, and allows for the creation of Python objects. Through this flaw in the ROS core package of actionlib, an attacker with local or remote access can make the ROS Master, execute arbitrary code in Python form. Consider yaml.safe_load() instead. Located first in actionlib/tools/library.py:132. See links for more info on the bug.

Technical Analysis

CVE-2020-10289 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
