## What is CVE-2025-67728?

CVE-2025-67728 is a critical command injection vulnerability in ShaneIsrael fireshare, published on 12 Dec 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Fireshare facilitates self-hosted media and link sharing. Versions 1.2.30 and below allow an authenticated user, or unauthenticated user if the Public Uploads setting is enabled, to craft a malicious filename when uploading a video file. The malicious filename is then concatenated directly into a shell command, which can be used for uploading files to arbitrary directories via path traversal, or executing system commands for Remote Code Execution (RCE). This issue is fixed in version 1.3.0.

Weakness: CWE-77 (Improper Neutralization of Special Elements used in a Command)
