⚠️ Risk & Real-World Impact
Worst Case
Attackers could upload malicious files, overwrite critical system files, or deface websites by exploiting broken access controls to gain unauthorized file management capabilities.
Likely Case
Unauthorized users could upload files they shouldn't have access to, potentially leading to content manipulation, defacement, or storage of malicious files on the server.
If Mitigated
With proper access controls and authentication checks, only authorized users can perform file operations, limiting the attack surface significantly.
🎯 Exploit Status
Exploitation requires understanding of the plugin's file management endpoints and bypassing authorization checks, but no authentication is needed beyond basic access to the WordPress site.
