Summary
Fleet is open source device management software. Prior to 4.81.0, a SQL injection vulnerability in Fleet's MDM bootstrap package configuration allows an authenticated user with Team Admin or Global Admin privileges to modify arbitrary team configurations, exfiltrate sensitive data from the Fleet database, and inject arbitrary content into team configs via direct API calls. Version 4.81.0 patches the issue.
