Summary
The 'clientId' parameter from incoming HTTP requests is directly concatenated into OAuth2 server log warning messages without sanitizing control characters. This allows an attacker to inject arbitrary content, including fake log entries, into the server's log files.
Risk Assessment
An attacker can manipulate server logs, potentially leading to data integrity loss and complicating security event monitoring and analysis.
Recommendation
Users are recommended to upgrade to versions 4.2.2 or 4.1.7, which fixes this issue.
