CVE-2025-15487
📋 TL;DR
The Code Explorer WordPress plugin up to version 1.4.6 contains a path traversal vulnerability in the 'file' parameter. This allows authenticated attackers with Administrator privileges to read arbitrary files on the server, potentially exposing sensitive information like configuration files, credentials, or source code. Only WordPress sites using vulnerable versions of this specific plugin are affected.

⚠️ Risk & Real-World Impact
Worst Case
Administrator-level attacker reads sensitive server files (e.g., wp-config.php, /etc/passwd, SSH keys), leading to full site compromise, credential theft, and lateral movement to other systems.
Likely Case
Malicious administrator or compromised admin account reads WordPress configuration files containing database credentials, potentially leading to database takeover.
If Mitigated
With proper access controls and monitoring, impact is limited to file disclosure within the web server's accessible directory structure.
🎯 Exploit Status
Exploitation requires authenticated Administrator access; path traversal via file parameter is straightforward once authenticated.
