## Technical details

The vulnerability is a deserialization-of-untrusted-data flaw in Aeon's load_rehab_pile_dataset method, resulting from insufficient validation of user-supplied input. The attack vector is local with user interaction required—an attacker must trick a user into opening a malicious file or visiting a malicious page. The attack results in arbitrary code execution in the context of the current process. A patch is available via GitHub commit 751918052c0cce266b4f7cd4b084408526efc015.
