⚠️ Risk & Real-World Impact
Worst Case
Attackers combine path disclosure with other vulnerabilities (like file inclusion or directory traversal) to achieve remote code execution, data theft, or complete system compromise.
Likely Case
Attackers gather reconnaissance information about server structure to plan more targeted attacks, potentially leading to information disclosure that aids in exploiting other weaknesses.
If Mitigated
Limited to information disclosure only, with no direct system compromise if other security controls prevent path traversal and file inclusion attacks.
🎯 Exploit Status
Exploitation requires triggering error conditions in the plugin to reveal full paths. This is typically done through malformed requests or accessing specific endpoints that generate errors.
