⚠️ Risk & Real-World Impact
Worst Case
Complete server takeover via remote code execution, allowing attackers to install backdoors, steal sensitive data, deface websites, or pivot to internal networks.
Likely Case
Attackers upload malicious files (disguised as images) and use LFI to execute them, gaining web shell access and compromising the WordPress site.
If Mitigated
If file uploads are strictly controlled and web application firewalls block LFI attempts, impact may be limited to information disclosure via file reading.
🎯 Exploit Status
Exploitation is straightforward - attackers can craft HTTP requests to trigger the vulnerable function with path traversal sequences.
