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.
The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
