WordPress Flozen < 1.5.1 - Arbitrary File Upload Vulnerability

The primary impact of CVE-2025-49071 is the ability for an attacker to upload arbitrary files to the web server. This includes web shells, which provide a remote command execution interface. Successful exploitation grants the attacker complete control over the affected server, enabling data theft, modification, and further lateral movement within the network. The blast radius extends to any sensitive data stored on the server or accessible through it. This vulnerability shares similarities with other file upload vulnerabilities where attackers leverage the ability to execute code on the server.

The primary mitigation for CVE-2025-49071 is to immediately upgrade Flozen to version 1.5.1 or later. If upgrading is not immediately feasible, implement strict file upload validation on the server-side to prevent the upload of executable files. Configure a Web Application Firewall (WAF) to block suspicious file uploads and detect attempts to execute uploaded files. Regularly scan the server for unauthorized files and monitor web server logs for unusual activity. After upgrading, confirm the vulnerability is resolved by attempting to upload a test file with a known dangerous extension (e.g., .php) and verifying that the upload is rejected.
