## Summary

Ultralytics, a popular computer vision software library, is affected by a flaw in its model-loading function that lets it process untrusted data unsafely. An attacker could exploit this by getting a user to open a malicious file or visit a malicious page, enabling them to run arbitrary code with the current user's privileges.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- Ultralytics: 8.4.65

## Description

Ultralytics torch_load Deserialization of Untrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ultralytics. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the torch_load function. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-29652.
