Technical details
The parse_model function in Ultralytics lacks proper validation of user-supplied strings before executing them as Python code, leading to code injection. The vulnerability requires user interaction (visiting a malicious page or opening a malicious file) and executes in the context of the current user. An attacker can leverage this to execute arbitrary code on the affected system.
