Description

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.

• CWE-89Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
