Description
CVE-2026-118617 is a high-severity vulnerability in Ultralytics version 8.4.65 involving deserialization of untrusted data in the load_dataset_cache_file function. This flaw allows remote attackers to execute arbitrary code if a user interacts with malicious content, such as visiting a crafted page or opening a malicious file. The vulnerability arises from improper validation of user-supplied data, enabling code execution in the context of the current user.
