Technical details
The vulnerability is a path traversal flaw in ZIP extraction logic that fails to properly validate file paths before extraction. An attacker can craft a ZIP-based update package with specially crafted paths to write files outside the intended directory. The attack requires user interaction (convincing a user to process the malicious package) but executes with the privileges of the OneCLI process.
