⚠️ Risk & Real-World Impact
Worst Case
Full server compromise through local file inclusion leading to remote code execution, sensitive file disclosure (including configuration files with credentials), and complete website takeover.
Likely Case
Sensitive information disclosure (database credentials, configuration files), limited file read access, and potential privilege escalation through file manipulation.
If Mitigated
Limited impact with proper file permissions, web server restrictions, and security controls in place, potentially only allowing read access to non-sensitive files.
