CVE-2026-72592: CWE-434: Unrestricted Upload of File with Dangerous Type in dulldusk phpfm
An unrestricted file upload vulnerability in dulldusk/phpfm through 1.8.0 allows an unauthenticated remote attacker to execute arbitrary PHP code on the server. The application ships with an empty upload extension filter ( = array) and no authentication enabled by default (auth_pass is empty string), allowing an unauthenticated attacker to upload a PHP webshell and execute it by browsing to the uploaded path.
AI Analysis
Technical Summary
CVE-2026-72592 is an unrestricted file upload vulnerability in dulldusk/phpfm up to version 1.8.0. The vulnerability arises because the application ships with no authentication enabled by default (empty auth_pass) and an empty upload extension filter ($upload_ext_filter = array()), allowing unauthenticated attackers to upload files of any type, including PHP scripts. This enables remote code execution by browsing to the uploaded malicious PHP file.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary PHP code on the server, leading to full compromise of confidentiality, integrity, and availability of the affected system. The CVSS 3.1 base score is 9.8, indicating critical severity with network attack vector, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, it is recommended to enable authentication and configure a restrictive upload extension filter to prevent uploading executable files. Avoid exposing the upload directory to direct web access or implement additional server-side validation and restrictions.
