CVE-2026-72592 is a critical-severity flaw (CVSS 9.8) affecting affected software. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- Critical severity
- CISA SSVC: automatable with total technical impact
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
